用准连续60 W半导体激光侧面泵浦Nd:YAG板条激光器，获得单脉冲能量3.5 mJ的激光输出，脉冲重复频率1～100 Hz，能量输出起伏小于±1%，光-光效率为15%，斜效率为29%。实现了声光调Q、电光调Q、BDN染料和LiF色心晶体被动调Q的激光输出，最大峰值功率超过100 kW。

The pulses with energy of 3.5 mJ,repeatition rate of 1～100 Hz and energy fluctuation less than 1% have been obtained of a slab Nd:YAG laser pumped by a quasi-CW 60 W laser diode array. The optical to optical efficiency is 15% and slop efficiency is 29%. The Q-switchings of the DPL involving A-O, E-O, and color center crystals and dye have been realized respectively. The maximum peak output power of the laser is 100 kW.
