以基于光场感生电离电子碰撞机制的类钯氙系统为例 ,计算并讨论了不同抽运激光偏振对等离子体的电离速率、阈值激光强度、电子在激光场中的剩余能量、各电荷态相对集居数、初始电子能量分布等电离参量的影响 ,计算结果表明 ,在相同的激光功率密度下 ,激光偏振对类钯氙 4 1.8nm 4d95d1S0 4d95 p1P1跃迁的X射线激光放大影响很大 ,圆偏振激光抽运更有利于类钯氙 4 1.8nm 4d95d1S0 4d95 p1P1跃迁的X射线激光放大的实现。 Taking the palladium-xenon-like system based on photon-induced ionization electron collisions as an example, the ionization rate, the threshold laser intensity, the residual energy of the electron in the laser field and the charge states of the plasmas are calculated and discussed. The results show that under the same laser power density, laser polarization has a great influence on the X-ray laser amplification of the quasi-Palladium xenon 4 1.8nm 4d95d1S0 4d95 p1P1 transition. The circular Polarization laser pumping is more conducive to the x-ray laser amplification of the quasi-palladium xenon 4 1.8nm 4d95d1S0 4d95 p1P1 transition.
