Picosecond high power extraction from an unstable resonator based injection-locked XeCl laser

Abstract

Single pulse peak power of over 0.3 GW with good beam quality was obtained from an injection-locked XeCl laser based on a positive branch confocal unstable resonator. The high power thus obtained has the potential of generating efficient high power tunable picosecond pulses from organic dyes in the UV and near UV region of the spectrum by pumping in a synchronous scheme.
