Slow and fast light propagation inside an optical cavity containing coherent atoms

Haibin Wu, Min Xiao

By balancing the steep linear and nonlinear dispersions of an intracavity electromagnetically induced transparency medium, the cavity transmission spectra can be significantly modified and controlled. As the cavity input intensity increases, the cavity linewidth changes from far below to above the empty cavity linewidth, corresponding to the photon propagation in the cavity from "subluminal" to "superluminal", respectively. A "white-light cavity" condition has been achieved under certain experimental conditions.By balancing the steep linear and nonlinear dispersions of an intracavity electromagnetically induced transparency medium, the cavity transmission spectra can be significantly modified and controlled.

All-cavity electromagnetically induced transparency and optical switching: Semiclassical theory

Aurélien Dantan, Magnus Albert, Michael Drewsen

The transmission of a probe field experiencing electromagnetically induced transparency and optical switching in an atomic medium enclosed in an optical cavity is investigated. Using a semiclassical input-output theory for the interaction between an ensemble of four-level atoms and three optical cavity fields coupled to the same spatial cavity mode, we derive the steady-state transmission spectra of the probe field and discuss the dynamics of the intracavity field buildup. The analytical and numerical results are in good agreement with recent experiments with ion Coulomb crystals [M. Albert et al., Nature Photon. 5, 633 (2011)].The transmission of a probe field experiencing electromagnetically induced transparency and optical switching in an atomic medium enclosed in an optical cavity is investigated.

High-resolution spectroscopy of weakly absorbing objects based on a competing beam method

Sergei A. Batishche, Vasili A. Mostovnikov, Anatolii N Rubinov

A new competing beam method is proposed for intracavity measurement of weak absorption. In this method two independent lasers with the same active medium are employed. An investigated sample is placed inside the resonator of one of the lasers with a narrow tunable emission line. In contrast to the selective intracavity absorption method, photoelectric recording of the spectra can be used in the proposed method and this can be done for narrow lines as well as for wide absorption bands. Moreover, the new method can be used to determine the two-photon absorption spectra.A new competing beam method is proposed for intracavity measurement of weak absorption.
