Efficiency optimization for Atomic Frequency Comb storage (2009)

Bonarota, M., Ruggiero, J., Gouët, J. -L. Le, Chanelière, T.

We study the efficiency of the Atomic Frequency Comb storage protocol. We show that for a given optical depth, the preparation procedure can be optimize to significantly improve the retrieval. Our...

Light storage protocols in Tm:YAG (2009)

Chanelière, T., Lauro, R., Ruggiero, J., Gouët, J. -L. Le

We present two quantum memory protocols for solids: A stopped light approach based on spectral hole burning and the storage in an atomic frequency comb. These procedures are well adapted to the...

Observation of Electromagnetically Induced Transparency and Slow Light in the Dark State - Bright State Basis of CPT (2009)

Lauprêtre, T., Ruggiero, J., Ghosh, R., Bretenaker, F., Goldfarb, F.

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 peculiar ground...

Coherent response to optical excitation in a rare-earth ion doped crystal (2008)

Ruggiero, J., Chanelière, T., Gouët, J. -L. Le

We investigate coherent propagation through a large optical density Tm$^{3+}$:YAG crystal. Using an ultra-stable laser, fiber filtering and site selection, we investigate the transmitted pulse...

Observation of Ultra-narrow Electromagnetically Induced Transparency and Slow Light using Purely Electronic Spins in a Hot Atomic Vapor (2008)

Goldfarb, F., Ghosh, J., David, M., Ruggiero, J., Chanelière, T., Gouët, J. -L. Le, ...

Electromagnetically induced transparency (EIT) is observed in gaseous 4He at room temperature. Ultra-narrow (less than 10 kHz) EIT windows are obtained for the first time for purely electronic spins...

HDN de la piridina con catalizadores de Ru/Al2O3 (1995)

Ruggiero, J., Scott, S.L., Portefaix, J.L., Lacroix, M., Breysse, M.

Central venous catheterization for parenteral nutrition.

Padberg, F T, Ruggiero, J, Blackburn, G L, Bistrian, B R

To define the risks associated with central venous catheterization for total parenteral nutrition (TPN) 3291 patient days of this therapy, delivered by an established nutrition support team, were...
