  • 对Schr?dinger方程引入修饰势,并将波函数展开为Floquet分波,即可实施分离变量。强光场时弱耦合法选取合适微扰量,径向波动方程可逐步近似求解。以圆极化强光场为例,计算了散射波函数、散射矩阵和截面。重要结论是:强光场下将出现多光子过程,对应m次多光子过程有相应的共振谱线族,谱线能量约为m?ω,并给出谱线强度计算公式。
    By introducing dressed potential and Floquet partial wave expansion of the wave functions, the Schr?dinger equation is made separable. In case of strong laser field, the radial wave equations can be solved step by step approximately through the weak coupling method in which an appropriate perturbation term is selected. As an example, with a circularly polarized laser field, the scattering wave function, S-matrix and the cross section are obtained. Important conclusions are: multiphoton processes will appear under strong laser field; m-th multi-photon processes must be connected with a corresponding class of resonance lines with energy near m?w. The formula of line intensity is also obtained.
