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。
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 prepumping with the pulsed modulated current the self Qswitched output laser with a controllable repetition rate is realized. Compare with the extracavity selfQswitched microchip laser the monolithic microchip laser possesses higher transform efficiency, more narrow pulse width and high repetition rate. Also such a laser constructed compact, and easy to be adjusted.
