Electromagnetically induced transparency with variable coupling-laser linewidth
نویسندگان
چکیده
Resonance transmission in a three-level L-type system of the rubidium D1 line is controlled by adjusting the linewidth of the pumping ~coupling! laser. With the change of pumping-laser linewidth from several MHz to about 100 MHz, the absorption reduction degrades from about 70% to less than 15%. The experimentally measured results are in good agreement with a simple theoretical calculation. @S1050-2947~97!09007-0#

Cavity-linewidth narrowing by means of electromagnetically induced transparency.
Cavity-linewidth narrowing in a ring cavity that is due to the high dispersion and reduced absorption produced by electromagnetically induced transparency (EIT) in rubidium-atom vapor has been experimentally observed. The cavity linewidth with rubidium atoms under EIT conditions can be significantly narrowed. Cavity-linewidth narrowing was measured as a function of coupling beam power.
متن کاملElectromagnetically induced transparency with Laguerre–Gaussian modes in ultracold rubidium
We demonstrate electromagnetically induced transparency with the control laser in a Laguerre–Gaussian mode. The transmission spectrum is studied in an ultracold gas for the D2 line in both Rb and Rb, where the decoherence due to diffusion of the atomic medium is negligible. We compare these results to a similar configuration, but with the control laser in the fundamental laser mode. We model th...
متن کاملEffects of a highly dispersive atomic medium inside an optical ring cavity
Atomic media inside an optical cavity can significantly alter the spectral response of the cavity. Both theoretical and experimental examinations are made of the cavity transmission with a highly dispersive intracavity multilevel atomic medium. It is found, owing to the reduced absorption and steep dispersion change accompanying electromagnetically induced transparency in such a multi-level ato...

In this paper, we present a method to generate continuous-variable-type entangled states between photons and atoms in atomic Bose-Einstein condensate (BEC). The proposed method involves an atomic BEC with three internal states, a weak quantized probe laser and a strong classical coupling laser, which form a three-level Λ-shaped BEC system. We consider a situation where the BEC is in electromagn...
متن کاملParametric dispersion in electromagnetically induced transparency
We analyze both experimentally and theoretically the phase shift of a fixed coupling laser field in a L-type system induced by a tunable probe laser field. The measurements are performed with a heterodyne interferometer on a beam of cesium atoms in the D2 line. This system exhibits electromagnetically induced transparency with a rapidly varying refractive index. The parametric dispersion of the...
