✦ Synopsis

We have demonstrated a passively Q-switched operation of Nd:GdVO4 laser in which a GaAs crystal is used as the saturable absorber for the ΓΏrst time as far as we know. A maximum average output power of 1:64 W was obtained at an incident pump power of 12 W, the corresponding optical conversion e ciency and peak power were 13.7% and 116:8 W, respectively. The maximum peak energy obtained in the experiment by 50% transmission couple was 19 J.
