Gas Laser

Gas lasers are a type of laser that use a gas mixture as the active medium to produce stimulated coherent radiation. They are classified under the supply class "Stimulated Coherent Radiation Devices, Components, And Accessories" in the supply group "Communication, Detection, And Coherent Radiation Equipment."

Gas lasers work by exciting the gas molecules in the mixture using an electrical discharge or other means. This excitation causes the gas molecules to emit photons, which are then amplified through the process of stimulated emission. The emitted photons are coherent, meaning they have the same frequency and phase, resulting in a highly focused and intense beam of light.

Gas lasers are commonly used in various applications, including scientific research, industrial manufacturing, medical procedures, and telecommunications. They are known for their high power output, narrow linewidth, and ability to produce laser light across a wide range of wavelengths.

Some examples of gas lasers include helium-neon (HeNe) lasers, carbon dioxide (CO2) lasers, argon-ion lasers, and excimer lasers. Each type of gas laser has its own unique characteristics and is suited for specific applications.

In addition to the gas laser itself, the supply class may also include components and accessories such as power supplies, cooling systems, optics, and control systems that are necessary for the operation and maintenance of gas lasers.

Overall, gas lasers are important tools in the field of coherent radiation and play a crucial role in various industries and scientific research.
