Development of mid-IR pulse shaping system for manipulating molecular dynamics

超短光脉冲形成为各种频率分量的相干叠加。通过独立地控制每个频率分量的相位，能够实现这种超短脉冲的任意波形合成。在这个项目中，我们开发了一种拓宽光谱的技术和一种能够在中红外范围内进行任意脉冲整形的系统。这一技术为观察和控制分子结构动力学提供了强有力的工具。

Ultrashort optical pulses are formed as a coherent superposition of various frequency components. Arbitrary waveform synthesis of such ultrashort pulses is enabled by controlling the phase of each frequency components independently. In this project, we have developed a technique to broaden the optical spectrum and a system which enables arbitrary pulse shaping in the mid-infrared range. This technique provides powerful tools in observing/controlling molecular structural dynamics.
