摘要

从理论上研究了单次强超短激光脉冲对氢分子离子的光碎裂反应。时间相关Schrödinger方程数值解的仿真结果表明，在光刻片光谱中存在量子干涉图样，且光刻片的诱导角分布对激光脉冲波长敏感。用光致锥的概念成功地解释了这些现象

Angular distributions of molecular photofragments by intense ultrashort laser pulses

We theoretically study the photofragmentation reaction of the hydrogen molecular ion by a single intense ultrashort laser pulse. Simulation results obtained from numerical solutions of time-dependent Schrödinger equations show that quantum interference patterns are constructed in the photofragment spectra and the induced angular distributions of photofragments are sensitive to the wavelength of the laser pulse. These phenomena are successfully explained by using the concept of the light-induced conical
