Abstract

We propose a new method for achieving simultaneous operation of laser mode locking and the Q-switch technique using only a single acousto-optic modulator (AOM) with a traveling wave; this AOM was placed inside the cavity of a green-emission Nd:YAG laser. The further shortening of the lasing pulse duration from 40 ps to less than 3.25 ps was obtained by the formation of a Kerr lens in a doubling-frequency crystal. At average output power of 1.5 W and pulse repetition rate of the Q-switch equal to 2 kHz, the peak power in a steady-operating laser exceeded 50 MW.
