✦ Synopsis

A diode-pumped Nd : YVO4 laser passively Q switched with GaAs is studied theoretically and experimentally. We have demonstrated the in uence of single-photon absorption, two-photon absorption and free-carrier absorption in GaAs on the Q-switched pulse characteristics. The pulse proΓΏle, pulse energy and pulse width of the Q switching with GaAs are simulated by using the conventional rate equations of the four-level laser system. The experimental results show reasonable agreement with the theoretical results on the whole.

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 cienc
