Correlated inhomogeneous absorption profiles across distinct optical transitions in a rare-earth doped crystal
Flora Segur, Sacha Welinski, Alban Ferrier +2
In rare-earth ion-doped crystals, inhomogeneous absorption profiles reflect the distribution of local environments experienced by individual ions. While each optical transition pro…
Analog phase-sensitive time-reversal of optically-carried radiofrequency signals
Thomas Llauze, Anne Louchet-Chauvet
Achieving low-latency time-reversal of broadband radiofrequency signals is crucial for reliable communications in dynamic, uncontrolled environments. However, existing approaches a…
Versatile, fast and accurate frequency excursions with a semiconductor laser
Thomas Llauze, Félix Montjovet-Basset, Anne Louchet-Chauvet
Achieving accurate arbitrary frequency excursions with a laser can be quite a technical challenge, especially when steep slopes (GHz/s) are required, due to both deterministic a…
Strain-mediated ion-ion interaction in rare-earth-doped solids
Anne Louchet-Chauvet, Thierry Chanelière
It was recently shown that the optical excitation of rare-earth ions produces a local change of the host matrix shape, attributed to a change of the rare-earth ion's electronic orb…
Limits to the sensitivity of a rare-earth-enabled cryogenic vibration sensor
Anne Louchet-Chauvet, Thierry Chanelière
Cryogenics is a pivotal aspect in the development of quantum technologies. Closed-cycle devices have recently emerged as an environmentally friendly and low-maintenance alternative…
Piezo-orbital backaction force in a rare-earth doped crystal
Anne Louchet-Chauvet, Pierre Verlot, Jean-Philippe Poizat +1
We investigate a system composed of an ensemble of room temperature rare-earth ions embedded in a bulk crystal, intrinsically coupled to internal strain via their sensitivity to th…
Deep and persistent spectral holes in Tm-doped yttrium orthosilicate for imaging applications
Caroline Venet, Benjamin Car, Lucile Veissier +2
With their optical wavelength in the near infrared (790-800nm) and their unique spectroscopic properties at cryogenic temperatures, thulium-doped crystals are at the center of many…
Optical study of the anisotropic erbium spin flip-flop dynamics
B. Car, L. Veissier, A. Louchet-Chauvet +2
We investigate the erbium flip-flop dynamics as a limiting factor of the electron spin lifetime and more generally as an indirect source of decoherence in rare-earth doped insulato…
Piezospectroscopic measurement of high-frequency vibrations in a pulse-tube cryostat
Anne Louchet-Chauvet, Rose Ahlefeldt, Thierry Chanelière
Vibrations in cryocoolers are a recurrent concern to the end user. They appear in different parts of the acoustic spectrum depending on the refrigerator type, Gifford McMahon or pu…
Ultrasound modulated optical tomography in scattering media: flux filtering based on persistent spectral hole burning in the optical diagnosis window
Caroline Venet, Maïmouna Bocoum, Jean-Baptiste Laudereau +3
Ultrasound modulated optical tomography (UOT) is a powerful imaging technique to discriminate healthy from unhealthy biological tissues based on their optical signature. Among the…
Selective optical addressing of nuclear spins through superhyperfine interaction in rare-earth doped solids
Benjamin Car, Lucile Veissier, Anne Louchet-Chauvet +2
In Er:YSiO, we demonstrate the selective optical addressing of the Y nuclear spins through their superhyperfine coupling with the Er electronic…
Optical measurement of heteronuclear cross-relaxation interactions in Tm:YAG
R. L. Ahlefeldt, M. F. Pascual-Winter, A. Louchet-Chauvet +2
We investigate cross-relaxation interactions between Tm and Al in Tm:YAG using two optical methods: spectral holeburning and stimulated echoes. These interactions lead to a reducti…
Optical memory bandwidth and multiplexing capacity in the erbium telecommunication window
Julian Dajczgewand, Rose Ahlefeldt, Thomas Böttger +3
We study the bandwidth and multiplexing capacity of an erbium-doped optical memory for quantum storage purposes. We concentrate on the protocol ROSE (Revival of a Silenced Echo) be…
Interlaced spin grating for optical wave filtering
Héloïse Linget, Thierry Chanelière, Jean-Louis Le Gouët +3
Interlaced Spin Grating is a scheme for the preparation of spectro-spatial periodic absorption gratings in a inhomogeneously broadened absorption profile. It relies on the optical…
Quantum memory for light: large efficiency at telecom wavelength
Julián Dajczgewand, Jean-Louis Le Gouët, Anne Louchet-Chauvet +1
We implement the ROSE protocol in an erbium doped solid, compatible with the telecom range. The ROSE scheme is an adaptation of the standard 2-pulse photon echo to make it suitable…
Adiabatic Passage and Spin Locking in Tm:YAG

In low concentration Tm:YAG, we observe efficient adiabatic rapid passage (ARP) of thulium nuclear spin over flipping times much longer than . Efficient ARP with long f…
Revival of Silenced Echo and Quantum Memory for Light
V. Damon, M. Bonarota, A. Louchet-Chauvet +2
We propose an original quantum memory protocol. It belongs to the class of rephasing processes and is closely related to two-pulse photon echo. It is known that the strong populati…
Comparison of 3 absolute gravimeters based on different methods for the e-MASS project
A. Louchet-Chauvet, S. Merlet, Q. Bodart +5
We report on the comparison between three absolute gravimeters that took place in April 2010 at Laboratoire National de Métrologie et d'Essais. The three instruments (FG5#209 from…
