The gas laser  was the first continuous-light laser and the first laser to operate on the principle of converting electrical energy to a laser light output. The first gas laser, the Helium–neon laser (HeNe), was co-invented by Iranian-Azerbaijani physicist Ali Javan and American physicist William R. Bennett, Jr. in 1960."] } } }
