HeNe Lasers The HeNe laser is 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.

You can also introduce tunable element like Lyot filter but this could be challenging as HeNe laser has somewhat low gain and therefore very sensitive to looses. The ZYGO designed and manufactured HeNe laser source is included standard in the complete line of visible wavelength laser interferometers, providing excellent performance, longest lifetime and lowest cost of ownership on the market.
