Laser systems, exhibiting energy conversion efficiencies greater than 20%, employ divalent metal halides, dissociated either electrically or optically, and pumped optically, usually by means of an arc lamp or an incoherent flashlamp. Either pulsed and continuous-wave lasing can be effected in or near the visible region.

Optically pumped divalent metal halide lasers

Unusual power enhancement and a plurality of output wavelengths in the visible or near-infrared regions are obtained simultaneously from a laser in which the vapors of two or more Group II-B metal halides are dissociatively excited either in an electrical discharge or by photodissociation by an external laser. By using halides involving only one metal and/or halogen isotope, the power output is greater than that obtainable with natural abundance salts. The laser output is also more confined spectrally. Over 50% of the power is contained in one or two spectrally narrow lines that are associated with a particular metal halide molecule.
