The most commonly used gas laser. The HeNe laser has an emission that is determined by neon atoms by virtue of a resonant transfer of excitation of helium. It operates continuously in the red, infrared and far-infrared regions and emits highly monochromatic radiation. Learn more about Helium Neon Laser...
One of the most common types of lasers, the HeNe laser uses a combination of helium and neon gas as its laser medium. Although the most common output wavelength is 632.8nm, HeNe lasers are available in several different wavelengths.
