Abstract

A simple procedure of dressing the atomic states distorted in the presence of a potential, bound or continuum, by a laser field is discussed, and the validity of the developed dressing procedure is tested by evaluating the harmonic generation and multiphoton ionization processes for a one-dimensional model potential of the form V(x) = −(1 + x2)−1/2. The results are compared with the exact one-dimensional model calculations of Eberly et al. for the same processes [ Phys. Rev. Lett. 62, 881 ( 1989)]. Several other dressed-state wave functions proposed by other authors are also tested.
