Paper Abstract

An experimental parametric study of a small volume x-ray preionized XeCl laser which uses the double discharge (spiker-sustainer) principle and a new fast ferrite magnetic switch is presented. This high-efficiency discharge excitation system, with a Ne/Xe/HCI mixture at relatively low pressure (P equals 2.5 atm.), in a 50 cm3 active volume (25(DOT)2(DOT)1 cm3), has made possible an efficiency of 3.2% in energy and 4% in power at maximum with up to 140 mJ of extracted optical energy in a 130 ns (FWHM) laser pulse in switch mode. The authors discuss laser characteristics dependence with magnetic switch and electrical circuit parameters, for switch mode. Future studies of the present advanced excitation system for conditions of very high PRF, in the frame of Eureka EU205 Eurolaser program, are presented. The experimental part of these planned studies will be made with LUX very high PRF high average power IMFM test-bed
