Gain measurements at 543 nm in helium neon laser discharges

A single-mode, frequency stable He-Ne laser operating on the 543 nm neon transition was used to probe an electrical discharge in helium-neon mixtures. Values for the optical gain at this wavelength were obtained. A comparison with the widely documented behaviour of the 633 nm transition shows a mark...

Summary:A single-mode, frequency stable He-Ne laser operating on the 543 nm neon transition was used to probe an electrical discharge in helium-neon mixtures. Values for the optical gain at this wavelength were obtained. A comparison with the widely documented behaviour of the 633 nm transition shows a marked difference in the variation of the optical gain with discharge pressure. This is shown to occur due to the differing behaviour of the lower laser state population densities with pressure. (Abstract uses original text)
