Spontaneously generated coherence induced second-order susceptibility in atomic gases
Spontaneously generated coherence induced second-order susceptibility in atomic gases
摘要
Abstract
Second-order susceptibility which vanishes in the electric-dipole approximation for an atom is induced by the spontaneously generated coherence (SGC). The SGC considered in a lambda-type atomic system causes an indirect coupling between the lower two levels which acts equivalently as a direct current (DC) field and therefore makes possible the existence of second-order susceptibility.
