Laser -等离子体相互作用的基础:主题选择

Basics of Laser-Plasma Interaction: a Selection of Topics

Andrea Macchi

摘要:

本文简要介绍了超高强度激光与等离子体相互作用的一些基本概念。选定的题目包括:(a)电磁场中电子的相对论动力学要素,包括有质动力和经典辐射摩擦;(b)“相对论”非线性光学透明度和自聚焦;(c)移动镜概念及其在光帆加速和高次谐波产生方面的应用,并说明有关的不稳定性; d)与从激光吸收能量、动能和角动量有关的一些特定现象。

英文摘要:

A short, tutorial introduction to some basic concepts of laser-plasma interactions at ultra-high intensities is given. The selected topics include a) elements of the relativistic dynamics of an electron in electromagnetic fields, including the ponderomotive force and classical radiation friction; b) the "relativistic" nonlinear optical transparency and self-focusing; c) the moving mirror concept and its application to light sail acceleration and high harmonic generation, with a note on related instabilities; d) some specific phenomena related to the absorption of energy, kinetic momentum and angular momentum from the laser light.
