Observation of Unidirectional Amplified Spontaneous Emission Induced by Velocity-Dependent Light Shifts

G. Petite, Bernadette Johnson, Wulfhard K. Lange, M. M. Salour

Publisher

Abstract

Laser-induced velocity-dependent light shifts have been used to compensate the Doppler broadening of an atomic transition. The unidirectional feature of this technique allowed us to observe a forward/backward asymmetry in the amplified spontaneous emission from an excited sodium vapor, switched on by a pulse of laser light.

Light-induced unidirectional light switching

M. M. Salour, G. Petite

We report the first observation of a unidirectionally emitting medium obtained by the method of Doppler compensation by velocity-dependent light shifts. The emission can be switched on by a pulse of laser light. The properties of this light-switching technique are experimentally demonstrated.

Experimental Evidence for Compensation of Doppler Broadening by Light Shifts

Serge Reynaud, M. Himbert, J. Dupont-Roc +2 more

Velocity-dependent light shifts may be used to suppress the Doppler broadening of an atomic spectral line observed along a given direction. We present emission spectra of $^{20}\mathrm{Ne}$ demonstrating the existence of such an effect for an appreciable portion of the atoms. Various possible applications taking advantage of the high anisotropy of this effect are suggested.

Observation of Light-Pressure-Induced Dispersion in Yb Vapor

Rudolf Grimm, J. Mlynek

We report on the observation of a light-pressure-induced dispersion of laser light interacting with a Doppler-broadened atomic medium. This novel dispersion feature displays an even symmetry with respect to the optical Doppler detuning; it is due to the small modification of the atomic velocity distribution caused by the spontaneous scattering force. Our phase-sensitive measurements were performed on the $\ensuremath{\lambda}=555.65$ nm $^{1}S_{0}\ensuremath{-}^{3}P_{1}$ transition in ytterbium vapor by the use of frequency-modulation spectroscopy. The experimental results are in good agreement with theoretical predictions.

Stimulated emission due to Doppler-free transitions in optically pumped lasers

A. K. Popov, Vladimir M. Shalaev

An analysis is made of conditions for achieving amplification due to transitions whose Doppler broadening is eliminated (under optical pumping) by light shifts which depend on the atomic velocity. An investigation is made of the spectral characteristics of this amplification process and of the features of lasing due to these transitions. The advantages of lasing due to this type of pumping are shown and possibilities for achieving unidirectional lasing in ring resonators are indicated.
