Abstract : A pulsed laser produces emitted laser energy by photodissociation of metal dihalide and cyclic recombination. A metal dihalide selected from sub-group II-B of the periodic table of elements is contained within an elongated sealed enclosure. Ultraviolet photons supplied from another laser employed as an excitation pump causes dissociation of the metal dihalide for achieving the ultimate laser action. An inert buffer gas is included within the enclosure for aiding photon energy transfer uniformity and to provide vibrational relaxation of the lasing medium in its electronic states. Two reflective surfaces, one of which is only partially reflective, are aligned with the principal axis of the laser assembly for producing an optical resonator for the emitted laser energy.
