Abstract:
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.
