摘　　要：为了研制一台灯抽运单级输出高能高重频脉冲Nd∶YAG固体激光器,采用理论分析影响激光器高能输出的主要参数,理论模拟输出功率与输入功率及反射率的关系,以及通过实验细节提高激光器效率等有效措施,研制出一台脉宽0.1m s^10m s可调,频率1Hz^1kHz可调的灯抽运脉冲Nd∶YAG激光器。该激光器在总注入电功率12kW时,输出最大单脉冲能量56 J,最大平均功率500W;光束参数乘积为16.5mm.mrad;总体电光转换效率4.2%;输出功率稳定性±2%。实验结果表明,采用的理论分析及实验模拟与实验结果基本吻合,获得了高能激光输出。In order to explore a 56J high-energy high-frequency lamp-pumped pulsed Nd： YAG solid-state laser, the main factors affecting the laser output were studied and the relation between the output power and input power and reflectivity was simulated. Then some effective measures were adopted to improve the efficiencies of the laser in experiments. As a result, a high energy Nd：YAG laser was obtained whose pulse width tunable between 0. 1 ms and 10ms, frequency tunable between 1Hz and 1kHz. When the laser inputs 12kW electrical power,its maximum single pulse energy was up to 56J, maximum average power is up to 500W with its beam parameter product 16.5mm · mrad, total electro-optics efficiency 4.2% , the stability of output power ± 2%. The experimental results are corresponding to the theoretical ones.
