We propose that selective reflectivity at a glass-gas interface be used to measure the elusive
frequency shift associated with the self-broadening of a gas of two-level atoms. We find that …

Intense light incident on a dense-gas–dielectric interface, from the dielectric side, is reflected
because of the combined effect of the discontinuities in the index of refraction at the interface …

A theory of selective reflection (SR) of a light beam from the interface of a dielectric medium
and a dense atomic vapor is presented. Following another earlier work on this subject [J …

We report the observation of atomic sublevel coherence from a quasi-twodimensional region
of atomic Na vapor near a glass surface. The ground state coherences are excited with a …

We present a calculation of selective reflection spectroscopy, in which the reflection
coefficient of a light beam from the interface of a dielectric and an atomic vapor is evaluated …

We study internal selective reflection from a dielectric-vapor interface, where three levels of
the vapor atoms in a Λ configuration are connected by two light frequencies. The reflectivity …

We calculate the modulation of the reflection coefficient for a frequency-modulated (FM) light
beam incident on the interface between a dielectric and an atomic vapor. The vapor is …

Absorption spectrum of a system of two closely spaced identical atoms displays, at certain
preparation, a dip that can be much narrower than the natural linewidth. This preparation …

We calculate the frequency shift due to resonant interaction between identical radiating
atoms. We give numerical results for particular geometries. In some cases the shift exceeds …

A theory for the spectral narrowing of selective reflection near a resonance line of an atomic
vapor is developed. The narrowing is ascribed to transient polarization behaviour of vapor …
