激光诱导氢原子吸收的响应函数研究
Study on the response function of absorption foratomic hydrogen induced by laser fields
摘要
Abstract
Split-operator method is used to the numerical solution of time-dependent Schr(o)dinger equation of one-dimensional hydrogen atom.The response function of absorption of atomic hydrogen driven by one-color extreme ultraviolet(XUV) light is studied.Compared the influence of results from empirical Gaussian and calculated exponential decay function,it is found that the response functions of absorption have no obvious change,except the quantitative values.Finally,the response function of absorption for atomic hydrogen driven by an infrared(IR) laser and a XUV light are calculated.The results are similar to ones for hydrogen driven by XUV light.It suggests the usual Gaussian decay function is simple,which does not need to calculate the excited lifetime of atom.关键词
