Intensity dependence of the photoelectric effect induced by a circularly polarized laser beam
Abstract
We show: (1) The photoelectric effect induced by a circularly polarized light beam is exactly equivalent to a quantum transition induced by a time independent perturbation between stationary states. The equivalent energy level of the target system is then light intensity dependent. (2) This energy shift, in the dipole approximation, is similar to that of a combined Zeeman-Stark effect in magnetic and electric fields perpendicular to each other.
