What are other manufactured wavelengths in Helium-Neon Laser?
Then what remembers while there is mention of a He-Ne laser is a red beam, those along with other wavelengths are manufactured,
a. Green of 543.5 nm, yellow of 594.1 nm, and orange of 611.9 nm He-Ne lasers are obtainable but are not nearly as efficient as the common red type as the spectral lines which require to be amplified are much weaker at such wavelengths.
b. Also IR (infra-red) He-Ne laser tubes are manufactured too at the IR wavelengths 1,152.3 nm and 3,391.3 nm. Such can be generated with considerable efficiency using suitable filters.
