Journal ArticleDOI
Anomalous ring-down effects and breakdown of the decay rate concept in optical cavities with negative group delay
T. Lauprêtre,Sylvain Schwartz,Rupamanjari Ghosh,Iacopo Carusotto,Fabienne Goldfarb,Fabien Bretenaker +5 more
TL;DR: In this article, a combined theoretical and experimental study of the ring-down oscillations in optical cavities filled with a medium with a sufficiently negative frequency dispersion to give a negative round-trip group delay time is presented.

Anomalous ring-down effects and breakdown of the decay rate concept in optical cavities with negative group delay
T. Lauprêtre,Sylvain Schwartz,Rupamanjari Ghosh,Iacopo Carusotto,Fabienne Goldfarb,Fabien Bretenaker +5 more
TL;DR: In this article, a combined theoretical and experimental study of the ring-down oscillations in optical cavities filled with a medium with such a strongly negative frequency dispersion to give a negative round-trip group delay time is presented.
Proceedings ArticleDOI
The solid-state ring laser gyro: current and future trends
Sylvain Schwartz,T. Lauprêtre,F. Goldfarb,Fabien Bretenaker,Rupamanjari Ghosh,Iacopo Carusotto,G. Feugnet,François Gutty,J.-P. Pocholle +8 more
TL;DR: In this paper, the authors report progress towards a high performance solid-state ring laser gyro using a diode-pumped Nd-YAG crystal as the gain medium.
Proceedings ArticleDOI
Interacting double dark resonances in a tripod system of room-temperature 4He
TL;DR: In this article, two different tripod configurations using metastable 4 He, with the probe perpendicular and parallel to the quantization axis, defined by an applied weak magnetic field, were experimentally studied.
Proceedings ArticleDOI
Ultranarrow coherent population oscillation resonance in a Λ-type system
T. Lauprêtre,Santosh Kumar,Perrine Berger,R. Faoro,Rupamanjari Ghosh,Fabien Bretenaker,Fabienne Goldfarb +6 more
TL;DR: In this paper, the authors reported the experimental observation of an ultranarrow resonance, as narrow as EIT ones, due to the transfer of coherent population oscillations to the lower states of a Λ-system.
