【摘要】 开展了二极管泵浦棒状Nd:YAG激光模块技术研究.在数值模拟激光模块增益分布的基础上对耦合结构进行了优化.初步研制出了高增益振荡级激光模块及高储能放大激光模块。实验结果表明.振荡级激光模块泵浦均匀且增益较高,TEM₀₀模输出情况下单脉冲能量为11.8mJ,光-光效率为15%;放大模块在500Hz重复频率下获得了单脉冲400mJ的储能。更多还原

【Abstract】 This paper investigates, theoretically and experimentally, the elements which influence the gain distribution of la-ser medium. A high gain laser module and a high energy storage laser module have been manufactured. The experiment results ap-proved that the high gain laser module was pumped uniformly and a TEM₀₀ output energy of 11. 8mJ was achieved at a light-lightefficiency of 15%H. In the high energy storage laser module, a 6mm diameter Nd:YAG rod which is 100mm long was pumped bynine-diode arrays （the peak pump-power is 6500kW）. Numerical calculation was done to optimize the distance between diode andNd: YAG. The experiment result approved that the gain coefficient of this module is 0.3/cm, and the storage power is 400mJ perpulse.更多还原
