Laser gas

The carbon dioxide gas laser is capable of continuous output powers above 10 kilowatts. It is also capable of extremely high power pulse operation. It exhibits laser action at several infrared frequencies but none in the visible. Operating in a manner similar to the helium-neon laser, it employs an electric discharge for pumping, using a percentage of nitrogen gas as a pumping gas. The laser beam is very narrow and can be concentrated on a very small area. This makes laser light highly directional. Vacuum Systems for Home-Built Gas Lasers.

Wave-guide CO2 laser is a very compact laser. Basically it has two electrodes separated by an insulator. Since the electrode separation is only a few millimeters, it acts as a bore of same dimension and the beam propagation is in the 'wave guide mode'. Normally sealed laser tube has a reservoir. High-pressure operation due to small bore allows rapid heat removal, leading to high gain and consequent high output. The beam diameter and divergence of the beam are 1 - 2 mm and 3 - 5 mrad respectively.Gas Lasers are used in applications that require laser beams with long coherence lengths, very high beam quality, or single mode operation. Gas Lasers are lasers that use an electric current discharged through a gas medium to produce a beam. Common Gas Lasers include helium neon, argon, or carbon dioxide. The type of gas used can determine or influence the laser’s wavelength, efficiency, or power. There are numerous applications for CO2 lasers. The ranges of power that can be produced by the CO2 laser, the relatively high efficiency, and low cost of the CO2 laser make it a very strong candidate for the materials industry as well as the medical profession.

The laser light spreads in a small region of space. Hence, all the energy is concentrated on a narrow region.Therefore, laser light has greater intensity than the ordinary light.

Until recently, dye head lasers were the only practical method of producing laser lines not easily available from other lasers, including the yellow and orange lines (580 to 610 nm). A dye head loaded with the laser dye rhodamine 6G could produce powerful laser lines in the 570 to 620 nm range for excitation of Texas Red, Cy5 or allophycocyanin (Loken et al., 1987). Many laser dyes are available, although only a few have been applied to flow cytometry. Recent advances in solid-state laser technology have largely replaced the dye head laser for flow cytometry.

This chapter describes the principles and characteristics of a number of gas lasers with medical applications. As examples of molecular infrared devices we describe the CO2 and CO lasers, which are capable of delivering high average powers or energetic pulses at a wavelength where tissues absorb strongly. Visible/near-ultraviolet (UV) wavelength lasers are important in medical treatments, and several gas lasers are useful sources in this region. Examples are the helium neon, the argon ion and the helium cadmium laser, all capable of producing continuous wave beams of good quality. The copper vapour laser is also described. In the UV and deep-UV spectral region gas lasers can generate short pulses of high peak power and high average power output. We cover UV excimer lasers and the pulsed UV nitrogen laser.Fast pulsing has proven to be more difficult. The simplest way to pulse the laser is to switch the RF power source to excite the CO2 plasma. Due to the high life time of the Laser output level (001) of the order of msec, a switching technique is possible for the production of higher peak power. With the correct duty cycle, one can produce pulses in the range of 100 microseconds to 10 ms. A shorter pulse is also possible by using an internal electro-optic modulator, such as a Q-switch (or cavity dumper). It is also very easy to actively Q - switch a CO2 laser by means of a rotating mirror or an electro-optic switch, giving rise to Q-switched peak powers up to gigawatts (GW) of peak power. Previously, Q-switching was limited to military and very high-value applications, because the limited availability of cadmium-telluride (CdTe) modulator crystals. Even then, the modulators had a short lifetime because of poor damage threshold properties of these crystals. However, recent innovations have eliminated these drawbacks. Now, a modulator with advanced growth techniques suitable for CdTe crystals produces devices with very high optical damage threshold. Properties of some resonantly absorbing molecules have also been experimentally investigated by making use of Q-switching techniques. SF6 has been used to passively Q-switch CO2 lasers.

Axetris uses proprietary technology-enhanced TDLS for gas detection, where a 0.05 nm narrow bandwidth diode laser beam is scanned across an absorption band of the target gas (figure 1), performing a high-resolution near-infrared absorption measurement. Electronic lock-in technology allows separating the gas absorption information from electro-optical system information, leading to a detection method eliminating the need for a physical reference channel and offering continuous sensor status monitoring. LASER stands for Light Amplification by Stimulated Emission of Radiation. A laser is a device which produces highly directional light. It emits light through a process called stimulated emission of radiation which increases the intensity of light.

Gas lasers are of different types: they are, Helium (He) – Neon (Ne) lasers, argon ion lasers, carbon dioxide lasers (CO2 lasers), carbon monoxide lasers (CO lasers), excimer lasers, nitrogen lasers, hydrogen lasers, etc. The type of gas used to construct the laser medium can determine the lasers wavelength or efficiency.C.K.N.Patel invented this molecular laser in 1964, at Bell Telephone Labs, USA. The active medium responsible for lasing is the carbon dioxide molecules, giving output at 10.6 μm and 9.6 μm. The very first CO2 laser produced only a few milliwatt output. CO2 lasers typically emit at a wavelength of 10.6 μm, but there are other lines in the region of 9-11 μm (particularly at 9.6 μm). In most cases, average powers are between some tens of watts and many kilowatts. The power conversion efficiency can be between 10 - 20 %. It is higher than for most flash lamp pumped solid-state lasers, but much lower than for diode pumped solid-state lasers. With the technological advancements, the present class of CO2 lasers produces CW output of megawatts. The salient features of fundamentals of lasing action in CO2 laser are as follows. Carbon dioxide molecule is a tri-atomic molecule consisting of two oxygen atoms covalently bonded to a central carbon atom. It has three fundamental modes of vibration, namely, symmetric, bending and asymmetric stretching modes, which are shown in figure below.

LGD F200 A NH3 Gas lasers in general are becoming much less common on commercial instrumentation. Most manufacturers of the large-frame argon- and krypton-ion lasers have begun to phase out production of these units, and support for these modules from the original manufacturers will likely cease in the near future. Several third-party companies, including Evergreen Laser (Durham, CT, USA, http://www.evergreenlaser.com) still provide support for these units, including tube fabrication and replacement. Air-cooled argon lasers are still being manufactured for legacy cytometers utilizing these units, but are rapidly being replaced by solid-state substitutes.Important property: Heat resistance. Chemical inertness. With its heat resistance and high chemical inertness, alumina also makes an excellent noncontaminating surface in furnace furniture. This is for exactly the same reasons that alumina makes an excellent analytical-grade crucible.

Gas Lasers

In gas lasers, the active medium is in the gaseous state. Since the laser media is a gas, it is kept in a plasma tube, with proper electrodes for electrical discharge to produce ionization, enclosed with dielectric mirrors. One may think that gas laser is a simple device, as there is no basic preparation required for the lasing medium, as in the case of a solid sate laser. But in practice, it is a complex device, as it needs optimization of gas mixture, gas discharge parameters, mirror and container configuration etc. The same have to be properly designed to create suitable conditions for population inversion. Further, gas discharge produces heat and it has to be removed to avoid detrimental effect on gas discharge and the optical components. Gas lasers may be grouped as, atom lasers, molecular lasers, ion lasers, etc. In the atom lasers, the lasing medium contains atoms, which are electrically neutral. He-Ne laser is an excellent example of this group. Molecular lasers have molecules as the lasing medium, as in the case of carbon dioxide, carbon monoxide and nitrogen lasers. Important ion lasers, such as argon and krypton lasers have ionized gases as their active laser medium. Interestingly, helium-cadmium laser has metal ions as the active laser medium. Some of the important lasers will be discussed in the coming paragraphs. Interested readers may look up the references, given at end of this section for detailed study.

The argon ion laser can be operated as a continuous gas laser at about 25 different wavelengths in the visible between 408.9 and 686.1nm, but is best known for its most efficient transitions in the green at 488 nm and 514.5 nm. Operating at much higher powers than the helium-neon gas laser, it is not uncommon to achieve 30 to 100 watts of continuous power using several transitions. This output is produced in a hot plasma and takes extremely high power, typically 9 to 12 kW, so these are large and expensive devices. In gas laser, the laser medium or gain medium is made up of the mixture of gases. This mixture is packed up into a glass tube. The glass tube filled with the mixture of gases acts as an active medium or laser medium.

A sealed off laser is a laser in which the ends of the gain tube are closed off and the gas is not allowed to flow into or out of the tube. The scheme of the Laser systems as a whole, at first seems rather simple; but the various details adopted for system life are quite complex. Contamination of the laser gas due to sputtering of the electrodes and production of heat are the major problems encountered in the working of the system. The electrodes must be made of a precious metal so that the continual material erosion does not react with the gases and especially with its disassociation products. In this case, heat is removed by helium removing the excess energy and moving to the walls of the gain tube where it gives up its energy to the wall through collisions. Another issue that arises in this case is that carbon monoxide is formed, which will cause laser action to cease. The addition of water vapour takes care that the formed CO gas will react with it and generates CO2 and finally re-mixes again with the CO2 gas. These types of lasers are capable of hundreds of watts of output power. Optimised systems achieve power outputs of up to 60 - 70 Watt per meter of discharged length. The cooling of gases takes place through diffusion- that means that the gas molecules diffuse from the center of the discharge to the wall, where they are cooled by collisions.Typical discharges are around 700 - 2000 volts, with current densities in the small-diameter bore (2 -mm) of the order of 3 - 5 amperes per square centimeter of cross section. Helium atoms in the laser gas absorb energy from the discharge and then transfer that energy to cadmium ions. The energy levels of cadmium and helium involved in the principal He-Cd lines are shown in the adjoining figure. The most prominent transitions, which can be easily, produced are 441.6-nm (blue transition) and the 325-nm (ultraviolet transition). The most important energy transfer mechanism for the narrow-bore tubes mainly used for blue and ultraviolet lasers is Penning ionization. Penning ionization is a form of chemi-ionization, an ionization process involving reactions between neutral atoms and/or molecules. The process is named after the Dutch physicist Frans Michel Penning, who first reported it in 1927. Chemi-ionization is the formation of an ion through the reaction of a gas phase atom or molecule with an atom or molecule in an excited state and should not be confused with chemical ionization. In Penning ionization, energy from an excited helium atom ionizes a cadmium atom:Semiconductor lasers are different from solid-state lasers.

The light waves from laser contain only one wavelength or color so it is known as monochromatic light.

CO laser technology was developed in the mid-1960s at the same time as CO2 lasers, says Andrew Held Consequently CO2 laser technology 'won' and has been the gas-laser standard since Continuous wave lasers provide the illumination source for our TIRFM systems. Typical laser types include gas, diode-pumped, and straight diode; all can be used in combination. The lasers are mounted on an optical breadboard with their polarity and vertical beam heights matched so that they can be combined into a single-mode fiber optic cable, which carries the light to the TIRFM illuminator on the microscope as schematically illustrated in Fig. 14.1.

Finally, this book will not overlook the historical context of the early developmental period, where the knowledge and groundwork were laid back in the 18th, 19th, and 20th centuries. This monograph is intended as a full update, spanning the full 70-year history of alumina ceramics, and its prehistory.The first solid-state laser was a ruby laser. It is still used in some applications. In this laser, a ruby crystal is used as a laser medium.The term 'white light laser' typically refers to one that is capable of producing a set of wavelengths which if mixed in the proper proportion can 'simulate' the effect of a white light source in full color displays and laser shows and also for some spectroscopy applications. However, they generally don't produce a broad spectrum like an incandescent light bulb. Though under some conditions krypton lasers as such can produce wavelengths over the full visible spectrum with lines in the red, yellow, green and blue. However, the most common white light lasers are large frame ion types with a mixture argon and krypton for the gas fill. White light lasers are now even available in air-cooled format. All use a mix of argon and krypton. Many are made for a roughly 60:20:20 ratio of red, green, and blue lines for proper white balance.

One should also mention the X radiation hazard emitted as a result of inappropriate protection of such components as lamps working with a voltage higher than 15 kV. Recent developments extending toward new spectral ranges into the deep UV and soft X as well as higher intensities and repetition rates are bringing new problems related to protection against X-radiation. Flash lamps in optical pumping pose a dual hazard. First, UV radiation is emitted if a quartz tube is used. Moreover, the quartz tube can explode on occasion, so they should be provided with covers. Another associated hazard is noise. The primary source of noise comes from the capacitor bank discharges.The most common and inexpensive gas laser, the helium-neon laser is usually constructed to operate in the red at 632.8 nm. It can also be constructed to produce laser action in the green at 543.5 nm and in the infrared at 1523 nm.For most live cell imaging we prefer to use a confocal microscope for the increased clarity, speed, sensitivity, and versatility offered by these systems. We use a three-channel Olympus Fluoview 500 laser-scanning confocal equipped with an argon ion gas laser (488 nm), a green helium neon laser (543 nm), and a red helium neon laser (633 nm). This laser combination allows us to excite GFP and RFP, as well as many commercially available fluorophores. In addition to scanning lasers, our system is equipped with a 100-W mercury light source focused along a separate light path for simultaneous imaging and UV uncaging of photosensitive compounds (see later).

Wavelength selection is accomplished using a software-controlled, acousto-optical tunable filter (AOTF). Because of the inadequate blocking power of the AOTF and the fact that gas lasers produce multiple usable (and unusable) wavelengths, extraneous excitation light must be blocked from reaching the extremely sensitive cameras used in TIRFM with “cleanup” excitation filters. On our systems, the cleanup filters are placed in a software-controlled filter wheel (FW) on the breadboard after the AOTF to provide versatility and to avoid reflection artifacts that occur if placed in the traditional location within the dichroic beam splitter housing (Fig. 14.1) (see Section 2.3.3).

Laser Safety Curtains - Large Area Laser Protection

Choose a refinement: Gas Equipment (4,999) Gas lasers are lasers with a gas (or plasma) as gain medium. A wide range of gas lasers has been developed for operation with a wide range of wavelengths and output powers In ion–gas lasers the gain medium is a plasma, an electrically conducting gas consisting of electrons and ions, produced by an electrical discharge. Here we will discuss the most representative ion–gas lasers including argon-ion and krypton-ion lasers. The argon-ion laser emits continuous radiation at powers from several milliwatts to tens of watts in the visible range, and several watts in the UV region. The main lines of the argon-ion laser emission are the green and blue lines corresponding to wavelengths of 514.5 nm and 488 nm, respectively. The strongest line of the krypton laser is at 647.1 nm. Lasers based on ions in plasma are facing stiff competition from solid-state lasers, but there are still many areas where they are used, including confocal microscopy, digital disk mastering, photolithography, and stereolithography.A variety of light sources have been used in clinical flow cytometers. The most used are arc sources (mercury compact arc lamp) and laser sources (continuous wave, argon-ion gas laser [UV, blue and green light], krypton ion gas laser [yellow and red light], helium–neon gas laser [red light], and the diode [red light] laser). Laser sources are principally used in modern flow cytometers. The advantages of a laser source are that they consist of a single color of light or an extremely narrow range of wavelengths. In addition, the waves comprising a laser beam are in “phase.” As a result, the beam of laser light is much more intense than that produced from incoherent light sources. The third advantage of laser light is directionality. The beam of light emerging from a laser is narrow and highly arranged in one direction, while light from ordinary sources is emitted in all directions.Straight diode and diode-pumped solid-state lasers can be up to 10 times smaller in size and are a noise- and heat-free alternative relative to their gas-driven equivalents. Straight diode lasers have a longer life expectancy relative to gas lasers whose tubes must be replaced (usually at a third of the full cost) every 2–3 years. Straight diodes can be modulated by software control, bypassing the need for an AOTF and thus can be directly linked to a fiber optic cable either at the laser head or, as in the case of our system, mirrored directly into a fiber optic coupler. It is important to note that the square beam shape of a typical diode laser usually results in an unavoidable and significant loss of power throughput at the point of fiber optic coupling. Diode-pumped lasers use a different technology to produce their monochromatic lines and their output must be modulated through an AOTF.

Advantages of laser based gas analysers:. High sensitivity (ppb, ppm concentrations) Interference free gas measurements Large dynamic range Absolute measurements no drift, no calibration.. The light waves of ordinary light sources have many wavelengths. Hence, the photons emitted by ordinary light sources are out of phase. Thus, ordinary light is incoherent.

Flue Gas Analyzer System <ZSJ> NOx, SO2, CO, CO2, O2. • Single-beam NDIR sensor with sample switching system + O2 sensor • Excellent zero-point stability • Continuous measurement of up to 5.. In gas lasers the gain-medium is a gas. Some of the gas lasers, such as the CO2 laser, the far-infrared molecular laser, and the chemical laser were discussed in sections 4.2.1, 4.2.2 and 4.3. These lasers operate on rotational and vibrational transitions. We shall now discuss gas lasers operating on electronic transitions like solid-state lasers. Gas lasers are facing stiff competition from solid-state lasers, but they are still powerful tools in many scientific, medical and industrial applications. We discuss here the most representative gas lasers including the helium–neon laser and the ion–argon laser.In semiconductor lasers, a p-n junction of a semiconductor diode forms the active medium or laser medium. The optical gain is produced within the semiconductor material. LAP Laser is one of the leading suppliers of systems that increase quality and efficiency through laser projection, laser measurement, and other processes Lasers are the preferred light source for the CSU because they provide a powerful, monochromatic, and coherent beam of light that can be launched into an optical fiber. While gas lasers such as argon ion and krypton–argon are adequate laser sources for SDCM, they require gas recharging after around 2000 h, have a large footprint, and incur high electrical loads. Over the last decade, a migration towards directly modulated (shutter-free) solid-state lasers has taken place (Gratton & vandeVen, 2006). A wide range of wavelengths (375–785 nm), powers (20–500 mW), and lifetimes (~ 10,000 h) are now attainable in compact enclosures referred to as “laser engines.” Moreover, laser engines can be purchased with multiple, fast-switching output fibers that allow the encased lasers to be shared for other modes of optical imaging such as total internal reflection fluorescence (TIRF) and fluorescence recovery after photobleaching (FRAP). Most laser engines now also allow for rapid gating of the lasers during the camera readout, to eliminate the streaking image artifacts due to exposure during the camera frame transfer cycle (Chong et al., 2004).

Detailed Images Packing & Delivery - Dangerous Goods.. 798 Gas Lasers from 51 Manufacturers meet your specification. Gas Lasers from the leading manufacturers are listed here. Narrow down on the list of Products by wavelength, type, technology.. The principle of operation and structure of the GVL is quite similar to CVL. Even the same laser tube and power supply can be used for both lasers. The only change is that instead of solid copper metal, gold wire is employed to produce gold vapour and it lases at 627.8 nm in the red region. The laser head can withstand a temperature of about 1700oC. The discharge circuit, like CVL, makes use of the thyratron. Typical efficiency of GVL (627.8 nm) is 0.2 % and the frequency doubled GVL (312.2 nm) is 0.02%. As compared to Copper Vapour Lasers, which can emit more than 200 W of average power, Gold vapour can produce few tens of Watts only. Gold vapour lasers find their main applications in dermatological and experimental cancer treatment of photodynamic therapy

We should mention another class of gas lasers that can exist in both versions—neutral and ionized-metal vapor lasers, which are based on a combination of a buffer gas such as nitrogen, helium, or neon, and the gaseous phase of a metal such as copper, gold, silver, or cadmium. They were more popular in the past, but strong competition from newer and more reliable technologies has led to a significant reduction in their applications. Today only the helium—cadmium and copper vapor lasers are still used in commercial applications.This shows the beams from two helium-neon lasers passing through two lenses arranged in the Galilean telescope geometry. The beams were made visible with a spray can of artificial smoke.The maximum attainable power output depends upon the efficiency of excitation and the cooling of the Laser gas. Thus the practical designs of the Laser vary according to the form of selective excitation, the cooling of the gas and with it the attainable power output. The development of a cost effective power Semiconductor for the high frequency region made it possible to realise high frequency excited discharging. They also have the advantage against parallel flow discharge as the power can be connected to the Laser gas almost without losses. The way the waste heat is rejected (or gas cooling method) has a large influence on the laser system design. In principle, it can be performed by two possible methods. The first method is based on the conventional process of natural diffusion of the heated gas to the tube wall, which is the operating principle of the sealed, and slow axial flow lasers. The second method is based on the gas forced convection, which is the operating principle of the fast flow lasers.

Edmund Optics offers a wide selection of lasers, including a variety of Gas Lasers such as HeNe, Argon-Ion, or CO2. Helium neon lasers are a multifunctional laser commonly used in many low power laser applications in education or laboratory settings. Argon-Ion lasers are ideal for applications in the near ultraviolet or visible. Carbon dioxide lasers are used in a variety of applications including molecular spectroscopy, gas sensing, environmental monitoring, or for testing night vision or thermal cameras. Semiconductor lasers do not belong to this category because these lasers are usually electrically pumped and involve different physical processes. In gas lasers the gain-medium is a gas.
