Abstract

InGaAs quantum wells and a Bragg mirror structure are grown on a GaAs substrate to simultaneously serve as a low-loss saturable absorber and an output coupler for highly efficient Q switching of a diode-pumped Nd:YAG laser operating at 946   nm . With an incident pump power of 9.2 W, the laser produces pulses of 38   ns duration with average pulse energy of as much as 20   μJ at a pulse repetition rate of 55   kHz .
