Phys. Rev. A 65, 063403 (2002) [5 pages]Spectral fitting method for the solution of time-dependent Schrödinger equations: Applications to atoms in intense laser fieldsReceived 6 February 2002; published 5 June 2002 A spectral fitting method for solving the time-dependent Schrödinger equation has been developed and applied to the atom in intense laser fields. This method allows us to obtain a highly accurate time-dependent wave function with a contribution from the high-order term of ▵t. Moreover, the time-dependent wave function is determined on a small number of discrete mesh points, thus making calculations simple and accurate. This method is illustrated by computing wave functions and harmonic generation spectra of a model atom in laser fields. © 2002 The American Physical Society URL:
