对于电子密度和增益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毛细管放电X射线在柱状长等离子体柱中的传播与增益过程 ,并给出了X射线激光的输出光强随偏转角的变化关系及偏离轴向的折射角。同时给出了X射线的饱和长度
For the plasma with linear distribution of electron density and gain, the propagation and gain of capillary discharge X-ray in the columnar long plasma column are studied by the simplified model under geometrical optical approximation. The output of X-ray laser Strong changes with the deflection angle and the deviation from the axial refraction angle. The X-ray saturation length is also given
