X射线激光在等离子体中传播过程的简化模拟研究

SIMPLE SIMULATION ON THE PROPAGATION PROCESSOF X RAY LASER IN PLASMA

对于电子密度为线性分布的等离子体，在几何光学近似下，通过简化模型研究了Ｘ射线激光的传播和增益过程，并给出了计算Ｘ射线激光的偏转角、发散角和最大光强的简单方法。其结果与理论模拟和实验结果都符合得比较好。

By virtue of a simplified model of gain region, the propagation and amplification of softxray within the plasma with linear electron density profile are studied in the geometrical optics approximation. A simple formulation evaluating the deflection and divergence angles and the maximum xray intensity are obtained. The results are in better agreement with experimetally measured data and numerically simulated results.
