KrF激光器空间非均匀抽运动力学模拟

KINETIC MODEL FOR SPACE NONUNIFORM PUMP IN A KrF LASER

提出了模拟KrF激光器的三维动力学方法 .该方法与以往的动力学方法的主要区别在于考虑了电子束抽运的空间非均匀性 .即将电子束抽运速率作为空间各点 (X ,Y ,Z)及时间 (t)的函数 .用三维模拟方法对 96 10 170 2实验进行了计算 .总的激光输出及镜面能量分布与实验符合相当好 .

A three-dementional(3D) kinetic model method for KrF laser is presented. The major difference between the method and the previous kinetic method for KrF laser is that the space nonuniform for the electronic pump is considered. The pump rate is considered as a function of 3D space (X, Y, Z) and time (t). Using the 3D model method, 96101702 experiment is simulated. The calculated laser energy output and lens energy distribution is in agreement with the experimental results. The problem that the calculated result of 1D model is obviously higher than the experimental result is solved.
