Progress on a short pulse excimer laser system with beam smoothing

摘要

A short pulse XeCl laser system is being developed for plasma physics and material science study. Partial spatial incoherence seed with short pulse is amplified by MOPA chain including three discharge pumped amplifiers and two electron beam pumped amplifiers for one beam. Final laser output of 5-10J in energy with pulse width of around 10ns has been achieved, which lays a good foundation for full scale construction.
