报道了二极管激光抽运Cr,Nd∶YAG被动调QNd∶YVO41064nm激光输出.为了提高被动调Q激光的输出稳定性,谐振腔采用长腔,增益介质位于谐振腔中间位置.实验中获得了稳定的被动调Q激光输出.在最高入射抽运功率为17.5W时,脉冲重复频率达到71.3kHz,脉冲宽度为0.4μs.调Q脉冲幅度不稳定性低于±10%,脉冲时间波动性低于±3.5%.
Reported the diode laser pumping Cr, Nd:YAG passively QNd: YVO41064nm laser output.In order to improve the output stability of the passive Q-switched laser, the resonator using a long cavity, the gain medium is located in the middle of the resonator in the experiment obtained a stable Passive Q-switched laser output with pulse repetition rate of 71.3kHz and pulse width of 0.4μs at a maximum incident pumping power of 17.5W Q-pulse amplitude instability less than ± 10% and pulse-time fluctuation less than ± 3.5%.
