ABSTRACT:
A metal vapour laser is disclosed having an optical cavity with a sputtering cathode and anode located at one end of the cavity. The sputtering cathode and anode includes a gaseous jet inlet to introduce a gas stream of inert gas into the optical cavity for entraining metal vapour sputtered by the sputtering cathode and anode. An electrical discharge separate to the sputtering cathode and anode is provided in the optical cavity for exciting the metal vapour entrained in the inert gas stream.
