The He-Ne laser is a relatively low power device with an output in the visible red portion of the spectrum. The most common wavelength produced by He-Ne lasers is 632.8nm, although two lower power (1.152 and 3.391um) infrared wavelengths can be produced if desired. The majority of He-Ne lasers generate less than 10m watts of power, but some can ...

He-Ne laser wavelength - PTC Community

The retardance is independent of the wavelength of the HeNe laser in air. It depends only on the wavelength in the quartz plate. As the temperature changes, the refractive index of the quartz changes, and so does the thickness of the plate. These effects are small though, and the refractive index of quartz is very accurately known.
