Abstract

High electrical and high chemical efficiencies were simultaneously achieved for the multikilojoule HF chemical laser using a Lambda-type (inclined type) electron beam initiation scheme. The optimum addition of NF//3 or SF//6 fluorine donor could increase both efficiencies and could reduce the total pressure of the laser gas mixture. The laser output obtained from the low-pressure mixture of H//2/F//2/O//2/NF//3 equals 30/208/62. 5/70 (Torr) was 4. 5 kJ in a 50-ns FWHM pulse width with an electrical laser efficiency of 226 per-cent and a chemical efficiency of 18. 5%.
