Abstract

Metal vapor laser apparatus includes an envelope within which is contained electrodes and a plurality of cylindrical copper segments arranged between them. During operation of the laser, bromine and helium buffer gas are arranged to flow through the envelope, causing copper bromide to be produced. When a discharge is established between the electrodes, the copper bromide vaporizes and dissociates to give copper vapor which is then excited to produce a population inversion. Such apparatus is able to operate at relatively low temperatures, in the region of 600.degree. C.
