In this work, we theoretically investigate the dynamic behaviors of a passively Q-switched Nd:YAG/Cr:YAG laser under rectangular wave pump modulation. The results show that, fixing the parameter of pump modulation, such as modulation amplitude ( A m ), modulation frequency ( f m ), unmodulated pump...
