Observation of noise phase locking in a single-frequency VECSEL
A. El Amili, V. Pal, F. Goldfarb +4
We present an experimental observation of phase locking effects in the intensity noise spectrum of a semiconductor laser. These noise correlations are created in the medium by cohe…
Anomalous ring-down effects and breakdown of the decay rate concept in optical cavities with negative group delay
T. Lauprêtre, S. Schwartz, R. Ghosh +3
Propagation of light pulses through negative group velocity media is known to give rise to a number of paradoxical situations that seem to violate causality. The solution of these…
Interacting double dark resonances in a hot atomic vapor of helium
S. Kumar, T. Lauprêtre, R. Ghosh +2
We experimentally and theoretically study two different tripod configurations using metastable helium (He*), with the probe field polarization perpendicular and parallel to the…
Photon lifetime in a cavity containing a slow-light medium
Thomas Lauprêtre, Cédric Proux, Rupamanjari Ghosh +3
We investigate experimentally the lifetime of the photons in a cavity containing a medium exhibiting strong positive dispersion. This intracavity positive dispersion is provided by…
