Phase-sensitive amplification via coherent population oscillations in metastable helium at room temperature

J. Lugani, C. Banerjee, M-A. Maynard +5

We report our experimental results on phase-sensitive amplification (PSA) in non-degenerate signal-idler configuration using ultra-narrow coherent population oscillations in metast…

Observation and measurement of an extra phase shift created by optically detuned light storage in metastable helium

M. -A. Maynard, T. Labidi, M. Mukhtar +4

Electromagnetically induced transparency (EIT) in metastable helium at room temperature is experimentally shown to exhibit light storage capabilities for intermediate values of the…

Optical phase dynamics in mutually coupled diode laser systems exhibiting power synchronization

Vishwa Pal, Awadhesh Prasad, R Ghosh

We probe the physical mechanism behind the known phenomenon of power synchronization of two diode lasers that are mutually coupled via their delayed optical fields. In a diode lase…

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…

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…

Observation of Electromagnetically Induced Transparency and Slow Light in the Dark State - Bright State Basis of CPT

T. Lauprêtre, J. Ruggiero, R. Ghosh +2

Electromagnetically induced transparency (EIT) is observed in a three-level system composed of an excited state and two coherent superpositions of the two ground-state levels. This…
