Abstract

The operation of pulsed diode pumped Nd:GdVO₄ and Nd:YVO₄ slab lasers in a bounce geometry in a free running and a passively mode-locked regime using a semiconductor saturable absorber was demonstrated. Higher efficiency of Nd:GdVO₄ in both regimes was achieved. In the free running regime the optical to optical efficiency of 28.3% was obtained with Nd:YVO₄ and 39.3% with Nd:GdVO₄ crystal in spatial mode close to TEM₀₀. In the passively mode locked regime the Q-switched and mode locked single trains containing 5 pulses were generated for a pump energy of 11 mJ from Nd:YVO₄ while the pump energy for Nd:GdVO₄ was only 5.5 mJ. The pulse duration was 48 ps and 65 ps respectively. Our results clearly demonstrate the advantage of using Nd:GdVO₄ in a pulsed free running and also a passively mode locked diode pumped regime in a bounce geometry.
