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100Hz重复频率时,实验获得单脉冲能量为51.9mJ的输出,光束质量M 2小于2,脉冲能量起伏小于2%, 实验结果与数值计算结果相符合。Abstract: 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 source. Over 51.9mJ energy per pulse at 100Hz repetition rate is achieved. Beam quality M2 is less than 2.The fluctuation of the laser output energy is less than 2%.The result shows that the experimental data have been consistent with the numerical calculation results.
