摘要: 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。

Abstract: 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.

Key words: x-ray laser, plasma, propagation gain
