Abstract

Using a pump-probe scheme with a large cloud of cold rubidium atoms, we observe very large double-pass gain (1800%) due to interference between Raman gain and four-wave mixing. A simple model explains the main features observed.

Mechanisms for Lasing with Cold Atoms as the Gain Medium

William Guerin, Franck Michaud, Robin Kaiser

We realize a laser with a cloud of cold rubidium atoms as gain medium, placed in a low-finesse cavity. Three different regimes of laser emission are observed corresponding, respectively, to Mollow, Raman, and four-wave mixing mechanisms. We measure an output power of up to 300 microW and present the main properties of these different lasers in each regime.

Observation of Raman-Gain Lasing and Four-Wave Mixing in Sodium Vapor

John F. Valley, G. Khitrova, H. M. Gibbs

The Doppler-broadened Raman gain of sodium vapor with a strong cw pump lases within a ring cavity. This lasing four-wave mixes with the pump to produce a third, complementary beam. Observations agree with theory only if atomic motion is included.

Observation of multi-Raman gain resonances in rubidium vapor

Jun Liu, Dong Wei, Jinwen Wang +4 more

We present an experimental study of multi-Raman gain resonances in a hot rubidium vapor. The experiment is performed based on a high-efficiency four-wave mixing process due to the Raman-driven coherence in a double-Λ configuration. The Raman gain resonance for 85 Rb atoms under a bias magnetic field is shown to be split into five or six peaks, depending on the orientation of the magnetic field. The formed multi-Raman gain resonances have potential applications in measurement of magnetic fields and generation of multi-frequency correlated twin beams.

Interplay Between Four-Wave Mixing and Six-Wave Mixing in Rubidium Atoms

Blake Anderson, Yanpeng Zhang, Min Xiao

Interference between four-wave and six-wave mixing signals is observed in a four-level atomic system due to atomic coherence. The experimental and theoretical conditions for generating such interesting effects are investigated.

Self-phase matched four-wave mixing in cold vapor

Joel A. Greenberg, Daniel J. Gauthier

We demonstrate novel four-wave mixing processes in a cold vapor that arise due to atomic spatial self-organization. This leads to a reduced parametric oscillation threshold and a more rapid increase of gain with pump power.

Macroscopic effects in stimulated Raman spectra

Li-Ya Pei, Zuo Zhan-Chun, Ling-An Wu +1 more

In stimulated Raman gain and loss spectra with the D1 line of an Rb85 atomic vapor system we observe experimentally that as the detuning of the pump field becomes larger, a probe beam can exhibit a sharp transition from gain to loss. We use the dressed-state model to explain this phenomenon as the consequence of polarization interference between atoms of different velocities, which have competing contributions to the probe beam.
