强电磁脉冲在非线性有质动力的作用下可以产生微弱的等离子体振荡。被捕获在尾流中的电子可以被加速到高能量。现有的功率密度为10 18 W/cm 2的玻璃激光器照射在密度为10 18 cm− 3的等离子体上，每厘米加速距离可以产生千兆电子伏的电子能量。这种加速机制是通过计算机模拟证明。加速器和脉冲发生器的应用程序进行检查。
An intense electromagnetic pulse can create a weak of plasma oscillations through the action of the nonlinear ponderomotive force. Electrons trapped in the wake can be accelerated to high energy. Existing glass lasers of power density 10 18 W/cm 2 shone on plasmas of densities 10 18 cm− 3 can yield gigaelectronvolts of electron energy per centimeter of acceleration distance. This acceleration mechanism is demonstrated through computer simulation. Applications to accelerators and pulsers are examined.
