Active media of exciplex lasers (review)

A review is given of experimental data on exciplex lasers. An analysis is made of the optical characteristics of lasing transitions, experimental conditions for achieving laser action, mechanisms of formation of the active level populations, character of nonequilibrium of the active medium, and proposed new active media. Detailed tables are presented with data on optical transitions, exciplex quenching rates, and characteristic parameters of the media and pump sources of existing lasers.
