| Abstract: | Developing status of combustion driving high power continuous wave Deuterium Fluoride(DF) chemical laser has been briefly presented. Structure parameters of HYLTE (Hypersonic, Low Temperature) nozzle and TRIP nozzle have been comparatively analyzed. Performance difference between the two kinds of nozzles has been summarized. Based on some correlational reported test data, output transverse modes of confocal unstable resonator corresponding to typical gain coefficient distribution along the flow field have been simulated by using numerical method. Considering technical maturity and reliability, we conclude that employing HYLTE nozzle is more appropriate than TRIP nozzle in research and development of high power DF laser concerning the two hard problems: uniformity of beam spot and load of mirrors. |
