激光尾流场加速器现已成为不可或缺的实验室工具。这是因为它们能够以紧凑的结构产生高能电子束。本文概述了激光尾流场加速的基本理论。考虑一维等离子体波，推导了尾流场产生的微分方程。考虑了低激光强度（）下尾流场产生的情况，以说明激光驱动器与产生的等离子体波之间的关系。最后考虑了等离子体波中的加速度。讨论了非线性和三维效应对等离子体波生长的重要性。
Laser wakefield accelerators are now becoming established as indispensable laboratory tools. This is because of their ability to produce high energy electron beams in compact configurations. Here we outline the basic theory of laser wakefield acceleration. One dimensional plasma waves are considered and the differential equation for wakefield generation is derived. The case of wakefield generation at low laser intensity () is considered to demonstrate the relation between the laser driver and the generated plasma wave. Finally acceleration in the plasma wave is considered. The importance of non-linear and three dimensional effects on the plasma wave growth are discussed.
