Statistical properties of resonance radiation selectively reflected from a cold semi-infinite medium

Abstract

The problem of the quantum-statistical properties of resonance radiation selectively reflected from unexcited media in the case where the photons are mutually correlated in the incident radiation flux is posed and solved. Allowance for mutual photon correlation precludes, in principle, solving the problem by perturbation methods. A quantum analog of the optical theorem of absorption, which causes an infinite subsequence of Feynman diagrams to vanish, is pointed out. The frequency-angle distribution of the photons in the reflected flux is predicted. The Fresnel formulas are reconstructed for the averaged reflection characteristics. The limits for their applicability in describing the reflection of mutually correlated photons are given. A suppression effect is predicted for the reflection of radiation from a laser source.
