Antibunching effects in resonant raman scattering involving laser fields of arbitrary strengths

Abstract

Using the recently developed theory of resonant Raman scattering in the presence of strong double frequency fields, the statistical properties of the spontaneously emitted Stokes and Rayleigh radiation are calculated. In particular, the temporal intensity correlations of arbitrary order are evaluated. It is found that they possess the property of factorization in terms of the probabilities for finding the system in the resonant intermediate excited state when the starting state is the given initial state and when the starting state is a particular superposition of the ground and final excited states. The weight-factors in the particular superposition depend on the direction of observation and on the transition dipole-moments. The second-order intensity correlation is shown to have the complete anti-bunching property. The factorization property of the intensity correlations is useful in the calculation of photo-electron counting distributions.
