Abstract
This paper describes recent results achieved in the development of a compact 1 kW XeCl laser GEFEST - 4, intended for using in various technologies. The laser was designed to obtain various output combinations of pulse energy (epsilon) and pulse repetition rate (f) with the same average output power P equals epsilon times f approximately equals 1 kW. Different excitation system for discharges with various cross sections are considered. Using the excitation system with UV preionization on the base of creeping discharge on dielectric surface we obtained an average output power of 1 kW at a pulse repetition rate of 100 Hz and 150 Hz (10 J multiplied by 100 Hz and 6.6 J multiplied by 150 Hz) with an efficiency of 1.65%. To obtain the combination of parameters 3.3 J multiplied by 300 Hz a spiker-sustained excitation system is developed which ensures in monopulse mode a pulse energy of 3.6 J with an efficiency of 3.6%. For this system the influence of macro- and micro-instabilities in discharge on energy and duration of the laser pulse is investigated. Capability of obtaining other combinations of epsilon and f at the epsilon multiplied by f approximately equals 1 kW is briefly considered.
