摘　　要：对二极管激光侧泵浦 Nd:YAG板条双程功率放大器进行了初步的研究 ,给出了激光器的数值模拟结果 ,建立了二极管侧面泵浦 Nd:YAG板条激光主振荡 -多程放大( MOPA)系统 ;在 1 0 0 Hz重复频率时 ,实验获得单脉冲能量为 51 .9m J的输出 ,光束质量 M2 小于 2 ,脉冲能量起伏小于 2 % 。Diode laser arrays side-pumped Nd:YAG slab double-pass laser power amplifier is studied in the paper. Experimental results and numerical simulations of laser performance are presented. MOPA system has been built up using Gaussian beam as a source. Over 51.9 mJ energy per pulse at 100 Hz repetition rate is achieved. Beam quality M2 is less than 2. The fluctuation of the laser output energy is less than 2%. Result shows that experimental data are consistent with the numerical calculation results.
