We study the bandwidth and multiplexing capacity of an erbium-doped optical memory for quantum storage purposes. We concentrate on the protocol revival of a silenced echo because it has the largest potential multiplexing capacity. Our analysis is app

Coherence rephasing is an essential step in quantum storage protocols that use echo-based strategies. We present a thorough analysis on how two adiabatic rapid passages (ARPs) are able to rephase atomic coherences in an inhomogeneously broadened ense

A theory of pulse transmission is presented in which the medium through which the pulse propagates is characterized by an inhomogeneous distribution that is either an atomic frequency comb (AFC) or a medium of randomly spaced frequency spikes (RSM).

We investigate the decoherence of ${\mathrm{Er}}^{3+}$ in ${\mathrm{Y}}_{2}\mathrm{Si}{\mathrm{O}}_{5}$ at low magnetic fields using the photon-echo technique. We reproduce accurately a variety of the decay curves with a unique coherence time by cons

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 insulators. Despite the random isotropic arrangement of dopants in the host cr

DIfferential Absorption Lidars (DIAL) can be powerful tools for remote detection of various gaseous species. We report here on the instruments that we have recently developed, based on specific optical sources, for industrial safety applications, as

Engine ignition using a laser requires very high peak power levels, that can be produced by solid-state lasers such as Yb:YAG passively Q-switched lasers. We developed high repetition rate diode pumped Yb:YAG micro-lasers to study the effect of cumul

We study photon echo generation in disordered media with the help of multiple scattering theory based on diagrammatic approach and numerical simulations. We show that a strong correlation exists between the driving fields at the origin of the echo an

We report on single-frequency all-fiber amplifiers based on PM Er-Yb doped P 2 O 5 -Al 2 O 3 -SiO 2 fibers. Peak power up to 700W at 1545nm for 730ns pulse duration has been obtained with a good beam quality and a 17dB PER was measured.
