本文综述了强激光激发的理论和实验研究现状，强激光激发是强激光物理和化学动力学之间的一个交叉领域，其潜在的应用范围从高次谐波产生和纳米级加工到立体动力学和化学反应的控制。在将强激光方法与其他对准技术结合起来之后，我们继续讨论这项技术的物理基础，并描述在实验室中观察它的方法。激光频率，脉冲持续时间和系统温度所起的作用进行了说明数值和实验。对准扩展到三维取向控制，一种阻止多原子分子绕所有三个轴旋转的方法。最后，我们讨论了强激光对准的潜在应用。
We review the theoretical and experimental status of intense laser alignment-a field at the interface between intense laser physics and chemical dynamics with potential applications ranging from high harmonic generation and nanoscale processing to stereodynamics and control of chemical reactions. After placing the intense laser approach in context with other alignment techniques, we proceed with a discussion of the physics underlying this technique and a description of methods of observing it in the laboratory. The roles played by the laser frequency, the pulse duration, and the system temperature are illustrated numerically and experimentally. Alignment is extended to three-dimensional orientational control, a method of hindering the rotation about all three axes of polyatomic molecules. We conclude with a discussion of potential applications of intense laser alignment.
