Efficient 'Foton' electric-discharge KrCl laser

The design of the 'Foton' electric-discharge laser, optimised for operation on the basis of KrCl* molecules, and its energy parameters were investigated. At λ = 222 nm the radiation energy was up to 250 mJ per pulse. The specific output radiation energy was 2.5 J litre^–1 and the laser efficiency was in excess of 0.8%. The possibility of further improvement of the characteristics of electric-discharge KrCl lasers are discussed.
