我们提出了一个深入的分析超快电子轨迹类型,产生阿秒电磁脉冲在两个反射和正向入射,相对论激光等离子体相互作用的过程中。我们的粒子模拟结果表明,对于一个目标,这是不透明的驱动激光脉冲的频率的发射轨迹是同步加速器,但显着不同,从以前确定的8字形,产生明亮的阿秒脉冲完全在反射方向。从驱动电磁场、等离子体的不透明性和正则动量守恒等方面解释了这种轨道类型的起源和特征。
We present an in-depth analysis of an ultrafast electron trajectory type that produces attosecond electromagnetic pulses in both the reflected and forward directions during normal incidence, relativistic laser-plasma interactions. Our particle-in-cell simulation results show that for a target which is opaque to the frequency of the driving laser pulse the emission trajectory is synchrotronlike but differs significantly from the previously identified figure-eight type which produces bright attosecond bursts exclusively in the reflected direction. The origin and characteristics of this trajectory type are explained in terms of the driving electromagnetic fields, the opacity of the plasma, and the conservation of canonical momentum.
