飞秒激光脉冲整形技术及其应用

摘要

By controlling the spectral amplitude, phase and polarization of the femtosecond laser pulse in the frequency domain, a shaped femtosecond laser pulse with almost arbitrary pulse shape in time domain can be obtained, and this femtosecond laser pulse shaping technique provides a new experimental tool to study the nonlinear interaction between light and atoms or molecules. In this paper, we introduce the development history, technical method, control technique and relevant applications of the femtosecond laser pulse shaping technique, and also carry out a prospect on the research trends of this technique.%通过频域上控制飞秒激光脉冲幅度、相位和偏振在时域上可以获得几乎任意形状的飞秒激光脉冲，这种飞秒激光脉冲整形技术可为研究光与原子分子非线性相互作用提供一种全新实验技术手段。本文介绍飞秒激光脉冲整形发展历史、技术方法、控制方式及其相关应用，并展望飞秒激光脉冲整形技术未来的发展方向。
