| 摘 要： | The asymptotic boundary condition to solve the time-dependent Schr dinger equation for a short-range model potential in an- intense laser field is presented. The condition is obtained by means of the asymptotic behavior of the short-rang emodel in the sufficiently large distance and Fourier transformation, and then the time-dependent Schr dinger equation is discretized into an inhomogeneous linear canonical equation. The inhomogeneous linear canonical equation is solved using the symplectic algorithm. The wavefunctions,time-calculatedevolution of the population on the bound state, and the high-orderharmonic generation verify that our numerical method is reasonable and effective.

| Abstract: | The asymptotic boundary condition to solve the time-dependent Schr dinger equation for a short-range model potential in an- intense laser field is presented. The condition is obtained by means of the asymptotic behavior of the short-rang emodel in the sufficiently large distance and Fourier transformation, and then the time-dependent Schr dinger equation is discretized into an inhomogeneous linear canonical equation. The inhomogeneous linear canonical equation is solved using the symplectic algorithm. The wavefunctions,time-calculatedevolution of the population on the bound state, and the high-orderharmonic generation verify that our numerical method is reasonable and effective. |
