Abstract

In this study, high efficient backward Raman compression has been achieved by a 10J KrF pump laser from Heaven-1 MOPA system using focused-beam geometry. A preliminary stage of experiments was carried out in CIAE with main results reported here. Up to 1.7J of first backward Stokes(268nm) output with pulse duration of 1.5ns was obtained as the pump (248nm) laser was 1OJ of energy and 22ns of pulse duration. The pulse duration is compressed by 15 times with total energy conversion efficiency up to 17%. The high conversion efficiency of backward SRS is considered mainly attributing to the focused geometry. The mechanisms of backward Stokes pulse self-shortening and forward-backward gain asymmetry compensating have been discussed. The backward Stokes pulse duration is considered to be much less than it was observed using a relatively lower bandwidth oscillograph. Further experimental research on precision time measurement will be performed later this year.
