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.

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. Tunable HeNe lasers are available for selecting from a range of wavelengths. 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.
