Contribution

It introduces a new self-consistent theory for reflection spectra and formulas for multiple reflections in dilute vapor cells.

Findings

Derived formulas for single and multiple reflections.

Obtained effective refractive index for selective reflection.

Results agree with experimental observations.

Abstract

In this paper we revisited the theory of selective reflection from a dilute vapor cell. A self-consistent theory was developed for reflection spectrum for Fabry-Perot interferometer. Formulas for single and multiple reflections were obtained. We also obtained the effective refractive index for a single selective reflection. The results of the paper are in a good agreement with existing experimental results.
