摘　　要：为了进一步提高激光器输出功率,针对脉冲串工作的2kJ高能量钕玻璃固体激光器,采用有限差分法,对比研究了传统恒温水冷方式和采用传统水冷与加热控制相结合的新型热管理技术下的激光棒温度分布情况。结果表明,采用新型热管理技术可以降低激光棒内的温度梯度,确保高能量激光输出。To get higher laser output, the temperature distribution of a pulsed 2kJ high energy Nd：glass solid-state laser was numerically studied by means of finite difference under two thermal management methods,i, e. , the traditional method with a fixed cooling water temperature, and the novel method with an altering water temperature. It is shown that the temperature gradient in the laser rod can he limited to a low level and higher energy could he outputted if the novel thermal management method employed.
