摘要：Passive Q-switching laser operation of Nd:GdxY1_xV04 mixed crystals at 671 nm has been compared in the same V-shape folded cavity. Based on our comparative analysis, the best laser characteristics - the highest pulse energy and peak power and the shortest pulse width - were demonstrated by Nd:Gd0.63Yo.37V04 crystal. At the same time, this crystal possesses the lowest thermal conductivity in comparison with the other Nd:GdxY!_xVO4 crystals, which could result in decreasing the average laser output power. To verify this assumption we also measured the focal lengths of thermal lens induced in the crystals during the laser operation.
