Gas lasers generally use the de-excitation of atoms, molecules or ions brought into an excited state, usually by an electric discharge process [AF 3 271] . These lasers are capable of delivering high power (several tens of watts continuously). However, because of their low conversion efficiency, they require high electrical power and efficient cooling, often...
