X射线激光在箔靶等离子体中传播过程的解析研究
ANALYTICAL STUDY OF X-RAY LASER PROPAGATION IN FOIL PLASMA

摘要: 对激光辐照箔靶产生的等离子体中X射线激光的传播和放大过程进行了解析的分析。在R.A.London物理模型的基础上, 用解析的方法描述了抛物线型电子密度分布增益纵剖面中X射线激光传播和放大过程的物理实质。指出了用最陡下降法求出的解析解中的误差, 并给出了折射长度的临界值。Abstract: Using London's model, physics of X-ray laser propagation and amplification in laser-plasma of the foil target is studied analytically. The analytical results agree well with London's numerical calculation. In accuracy of steepest-descents-approximation adopted in London's calculation was found.
