X-ray laser based on OFI is a promising way to realize the table-top X-ray laser.A simple model to describe the electron energy distribution in plasma produced by circularly polarized optical-field-induced ionization is constructed on the basis of ADK tunneling ionization theory.The ionization rate,threshold intensity,residual energy and electron energy distribution of Pd-like Xe system based on optical-field-induced ionization are calculated.The results are useful to further experments on X-ray laser of Pa-like Xe system. 相似文献

等离子体波导中光场感应电离软X射线激光研究进展 总被引:2,自引:0,他引:2
利用等离子体波导实现光场感应电离(OFI)X射线激光放大,一方面可以降低产生X射线激光的抽运激光阈值,从而提高由于自散焦而降低的有效激光功率密度;另一方面,由于等离子体中产生的大量电子被束缚在等离子体波导内,降低x光信号色散影响,可以大大提高激光增益长度,这是一种实现台上X射线激光新的抽运机制.详细介绍了光场感应电离x射线激光、强激光等离子体波导以及等离子体波导中光场感应电离X射线激光的研究进展. 相似文献
