研究强激光脉冲与一维多原子分子离子的相互作用,讨论双色激光场中高次谐波转化效率的提高,并应用经典三步模型说明高次谐波平台展宽的物理机制.
Interaction of multi-atom molecular ions with intense laser pulse is studied. High-order harmonic generation plateau is extended and conversion efficiency is enhanced. Physical mechanism of plateau extension is explained with classical theory.
