Heating rate measurement and characterization of a prototype surface-electrode trap for optical frequency metrology
Thomas Lauprêtre, Bachir Achi, Lucas Groult +4
We present the characterization of a prototype surface-electrode (SE) trap as a first step towards the realization of a compact, single-ion optical clock based on Yb. The use o…
Controlling the potential landscape and normal modes of ion Coulomb crystals by a standing wave optical potential
Thomas Lauprêtre, Rasmus B. Linnet, Ian D. Leroux +3
Light-induced control of ions within small Coulomb crystals is investigated. By intense intracavity optical standing wave fields, subwavelength localization of individual ions is a…
Localization of ions within one-, two- and three-dimensional Coulomb crystals by a standing wave optical potential
Thomas Lauprêtre, Rasmus B. Linnet, Ian D. Leroux +2
We demonstrate light-induced localization of Coulomb-interacting particles in multi-dimensional structures. Subwavelength localization of ions within small multi-dimensional Coulom…
Light storage via coherent population oscillation in a thermal cesium vapor
A. J. F. de Almeida, J. Sales, M. -A. Maynard +5
We report on the storage of light via the phenomenon of Coherent Population Oscillation (CPO) in an atomic cesium vapor at room temperature. In the experiment the optical informati…
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…
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…
