Abstract

A nanosecond 1.3μm Nd:YAG laser-pumped external cavity eye-safe Raman laser based on BaWO4 crystal is efficiently demonstrated. The average power of 1.5μm was 0.60W operating at a pulse repetition rate of 1.7kHz and an incident pump power of 4.14W. Conversion efficiency of 14.5% and a high slope efficiency of 54.5% have been achieved. Pulse shortening was obviously observed. The pulse duration of the first Stokes was about 40ns, much shorter than the fundamental pulse with a duration of 220ns.
