摘要

A Nd:YAG laser passively Q-switched by a Cr:YAG showed a high single pulse energy of 53.0 mJ and 5.1 MW peak power. The laser was pumped by quasi-continuous-wave diode bars from single side. The Q-switched pulse had optical-to-optical efficiency of 12%and average temporal duration of 10.4 ns when Cr:YAG with initial transmission of 9.0%was used. Intense pumping as well as very low initial transmission of the saturable absorber gave very high peak power.
