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.
Abstract
This paper investigated, theoretically and experimentally, the elements which influenced the gain distribution of laser medium. A high gain laser module and a high energy storage laser module have been manufactured. The experiment results approve that the high gain laser module is pumped uniformly and a TEM00 output energy of 11.8 mJ is achieved at a light-light efficiency of 15%. In the high energy storage laser module, a 6 mm diameter Nd:YAG rod which was 100 mm long was pumped by nine-diode arrays (the peak pump-power was 6500 kW). Numerical calculation was done to optimize the distance between diode and Nd:YAG. The experiment result approves that the gain coefficient of this module is 0.3/cm, and the storage power is 400 mJ per pulse.
