摘要
为了指导毛细管放电激光器的实验 ,建立了电子密度和增益为抛物线分布的等离子体理论模型 .在几何光学的近似下 ,对毛细管放电X射线在柱状长等离子体柱中的传播与增益过程进行了解析分析 ,并给出了抛物线近似下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和折射长度 ,并将理论结果与Rocca小组的实验结果进行了比较 ,理论与实验吻合的相当好 .
To facilitate the capillary discharge laser experiments,a simplified model has been established for the gain region,the propagation and amplification of capillary discharge X-ray within the cylindrical plasma in the form of parabolic eletron density profile for analitical study by geometrical optics approximation. The angle of refraction and the relation between out-put intensity and deflection angle and deflection length are established. The theoretical results are in good agreement with the experimental results of Rocca group.
