摘要
报道了一种高功率准连续运转的全固态Nd∶YAG激光器。采用Nd∶YAG晶体板条作为增益介质,平凹腔型作为振荡腔,激光沿Zigzag光路在板条内传播。当抽运功率为9 kW时,振荡可获得平均功率为3420 W的激光输出,重复频率为1 kHz,激光脉宽为80μs,单脉冲能量为3.42 J,经过校正后的光束质量β为4.1倍衍射极限。
An all-solid-state quasi-continuous-wave(QCW)Nd∶YAG slab laser with a high power was demonstrated.A Nd∶YAG slab crystal is adopted for gain medium,a plane-concave cavity is set up,and the laser beam travels along a Zigzag path in the slab.An average output power of 3420 W is obtained at a pump power of 9 kW,corresponding to a repetition rate of 1 kHz.The pulse width is 80μs with a pulse energy of 3.42 J,and the laser beam quality with AO system β is 4.1 times of the diffraction limit.
