946 nm 25 mJ/3 ns Nd:YAG laser based on regenerative amplification of pulses

Abstract

Regenerative amplification of 946 nm pulses which are sliced from 12 mW continuous wave laser diode is reported. Near‐transform‐limited 2.9 ns pulses with highly stable and smooth temporal shape were obtained with the energy of 25 mJ/50 Hz and M2 < 1.2.
