Abstract

We report for the first time the actively Q-switched laser performance of a class of mixed Nd:Gd x Y1−x VO4 crystals. In comparison with the ordered Nd:GdVO4 and Nd:YVO4, an enhancement in both pulse energy and peak power is demonstrated in the low pulse-repetition frequency (PRF) range of 5–20 kHz, confirming Nd:Gd0.64 Y0.36VO4 as the most advantageous in this respect. Laser pulses of 8.3-ns duration are generated at PRF=10 kHz with pulse energy and peak power being respectively 171 μJ and 20.6 kW. While for high-PRF operation (>∼40 kHz), the ordered Nd:GdVO4 and Nd:YVO4 prove to be superior to the mixed crystals.
