Abstract

Modifying the output pulses of a passively Q-switched Nd:YAG laser, operating at $1064\mathrm{nm}$, was realized by heating the laser crystal. With the demonstrated laser setups, a $100\mathrm{K}$ temperature rise led to a more than 50% increase in the pulse energy and a more than 10% decrease in the pulse length. This method offers an effective way to tune the output of the laser without mechanical adjustment or a change of components.
