A New Spectral Fitting Method and Its Application to High Order Harmonic Generation Spectra of Hydrogen in Intense Laser Field

  • 摘要: 介绍了一种新的求解含时薛定谔方程的谱拟合法 .该方法把含时波函数在少量且分布稀疏的网格点上拟合 ,结合泰勒级数展开 ,用相对简单的计算得到包括Δt高次项贡献的含时波函数 .并将这一方法用于强激光场中氢原子高次谐波谱的计算 ,得到了与其它方法一致的结果. A new spectral fitting method for solving the time-dependent Schrdinger equation has been developed and applied to the atom in intense laser fields. By using this method, the time-dependent wave functions are determined with few and far between discrete mesh points. And the high accuracy wave functions with contribution of high-order-term of Δt are obtained by using Taylor series expand method. Our method is proved by computing high order harmonic generation spectra of hydrogen in laser fields...
