摘要: 利用激光二极管泵浦双掺杂YAG微片晶体，在连续泵浦时获得了重复频率为2.78kHz，脉冲宽度为6ns的自调Q激光输出。并通过预泵浦加脉冲调制电流的方法，实现可控重复率的自调Q脉冲输出。与外腔式自调Q微片激光器相比，这种一体化微片激光器具有更高的转换效率、更窄的输出脉冲宽度和更高的重复频率，同时结构更为简单紧凑，易于调整。Abstract: Using the Cr4+:Nd3＋:YAG microchip pumped by LD, the self Qswitched laser pulses with the repetition rate of 2.78kHz and pulse width of 6ns are obtained in the CW case. Through the pre-pumping with the pulsed modulated current the self Qswitched output laser with a controllable repetition rate is realized. Compare with the extra-cavity selfQswitched microchip laser the monolithic microchip laser possess higher transform efficiency, more narrow pulse width and high repetition rate. Also such a laser constructed compact and easy to be adjusted．
