该文研究的是两束相向超短超强激光脉冲与中间薄膜靶相互作用之后产生快电子的一种简单自洽模型理论 .由理论推知 ,当满足一定条件时 ,由于激光有质动力与靶电子的谐振作用 ,在靶表面的电子云层中的电子被强烈加速产生快速高能电子
In this paper, we study a simple self-consistent model theory of fast electrons generated by the interaction of two bundles of ultrashort superlattice laser pulses with an intermediate thin film target.It is deduced from the theory that when a certain condition is satisfied, The resonance of the electrons, the electrons in the electron cloud layer at the target surface are strongly accelerated to produce fast high-energy electrons
