对激光二极管泵浦、声光锁模、调q Nd:YAG激光器进行了参量研究。通过对像散补偿腔内光斑大小的分析，为纵向抽运激光棒的热透镜提供了充分的补偿。利用腔内标准子将每脉冲输出能量为0.5 nJ的锁模脉冲的宽度延长至910 ps。输出能量（±3%）和峰值功率（±5%）具有良好的稳定性，与闪光灯泵浦锁模调q激光器相当。
The parametric studies of a laser-diode (LD)-pumped, acousto-optic (AO)-mode-locked and Q-switched Nd:YAG laser were carried out. Adequate compensation for the thermal lensing in the longitudinally pumped laser rod was provided by analyzing the spot size in the astigmatically compensated cavity. The width of the mode-locked pulse with 0.5 nJ output energy per pulse was elongated to 910 ps by means of an intracavity etalon. Good stabilities of the output energy (±3%) and the peak power (±5%) were obtained, which are comparable to those of the flash-lamp-pumped mode-locked Q-switched lasers.
