摘　　要：以c切Nd:YVO4为自拉曼晶体,c切Nd:GdVO4作为拉曼晶体,KTP腔内倍频,采用声光调Q,实现基于两种拉曼晶体共有的259 cm−1次级频移的脉冲二阶斯托克斯光1129 nm激光的有效振荡和腔内倍频,首次获得有效564 nm黄绿脉冲激光输出。在5.83 W的入射泵浦功率下,脉冲重复率为10 kHz时,564 nm激光最高平均输出功率226 mW,脉冲宽度为5.7 ns。Based on a c-cut Nd:YVO4 as the self-Raman crystal and a c-cut Nd:GdVO4 as the Raman crystal, second-Stokes light at 1129 nm corresponding to the secondary Raman shift of 259 cm−1 generated and was intracavity frequency-doubled with a KTP crystal, and effective output of 564 nm yellow-green pulsed laser was achieved from a acousto-optic Q-switched resonator for the first time, to the best of our knowledge. At an incident pump power of 5.83 W and a pulse repetition rate of 10 kHz, the highest average output power of the 564 nm laser reached 226 mW, with a pulse width of 5.7 ns.
