Coherence relaxation during the diffusion of resonance radiation in media with a magnetic field
Abstract
The kinetic Green's function method is used to obtain equations which describe the transport of resonance radiation in magnetic fields for arbitrary ratios between the natural width γ, the Doppler width Δ ω _{D}, and the Zeeman splitting of the excited atomic levels. It is shown that as Δ ωD/ γ→0 the equations become very much simpler and in particular cases admit an exact solution. In particular, the decay of coherence in an infinite homogeneous space is characterized by five relaxation times, which are defined by a system of algebraic equations.
