We present a laboratory demonstration of the Kramers-Kronig relation between the resonant
absorption and refractive index in rubidium gas. Our experiment uses a rubidium vapor cell …

We investigate the determination of atomic density and collisional broadening for a heated
cesium vapor. The proposed technique is based on the interferometric signal between …

Two experiments are presented which measure atomic properties using an atom
interferometer. The interferometer splits the sodium de Broglie wave into two paths, one of …

The refractive indices of rare gases have been measured by Fabry-Perot interferometry
down to 140 nm. Dispersion relations of the Sellmeier form are given and the results are …

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 …

We discuss the theory and error analysis for an ultrasensitive refractive index detector based
on the two-frequency Zeeman effect laser. Experimental measurements on gases agree …

We have performed the first detailed calculation of the index of refraction of a gas (argon) for
an atomic wave (sodium). The index depends rapidly on the wave vector kr describing the …

Atomic vapors make flexible and useful nonlinear optical media when light is detuned far
from resonances. However, few direct measurements of their nonlinear coefficients have …

The apparatus in precise scanning-wavelength interferometry with gases is described. The
dispersion of the refractive index is measured with the aid of an evacuated Michelson …

A new method for accurately measuring the dispersion of the refractive index of gases is
presented. The technique makes use of the phase-matching condition which applies to a …
