Research Interests
M. Ducloy’ research interests are centred on basic processes of laser-matter interactions, and their applications in laser spectroscopy and metrology, nonlinear and quantum optics, laser control of atom motion and matter-wave optics, cavity QED processes and nano-optics.
After a thesis work on optical pumping with lasers, he turned to the analysis of resonant nonlinear optics and four wave mixing processes in dilute vapours or gases. In 1977, he carried out the first experimental demonstration of coherent inversion-less amplification in two-level systems at optical frequencies, work now considered as the starting point of the field of inversion-less amplification and lasing. He also demonstrated the huge potentiality of resonant vapours in optical phase conjugation, and image aberration correction via degenerate four-wave mixing (DFWM). Among many works performed: the study of basic processes involved in saturated phase-conjugation and the demonstration of dominant dispersive character of the atomic response (1982); the demonstration of very large efficiency (>100%) in phase-conjugate reflectors, leading to self-induced phase-conjugate oscillation in atomic vapours and opening the way to a new class of nonlinear unstable and chaotic behaviours using DFWM processes in resonant media; prediction and demonstration of optical phase conjugation with frequency doubling, via higher-order non degenerate multi-wave mixing.
M. Ducloy pioneered the use of DFWMP to devise high-frequency shot-noise-limited optical heterodyne laser spectroscopy. Among many developments (frequency stabilisation and metrology…), a major one has been in high-resolution atomic spectroscopy at gas-solid interfaces -nonlinear spectroscopy and saturated absorption with evanescent waves-, and later in Doppler-free reflection spectroscopy - work which is the starting point to a series of studies developing a laser-spectroscopy approach to atom-surface interactions and cavity QED experiments. The key work has been a case of textbook experiment, demonstrating the van der Waals (vW) long-range attraction between atom and surface, and based on spectral monitoring of the surface-induced red-shift of the atomic response, in straight reflection spectroscopy at normal incidence on a dielectric-vapour interface (1991). Many works followed in this cavity QED field, analysing all the properties of atom-surface interaction (e.g., atom adsorption-desorption dynamics, surface re-distribution of gas atom velocities, etc). This culminated (1999) with the surprising demonstration that the basic vW attraction between neutral bodies can be turned into a long range vW repulsion, when the internal dynamics of the polarisable systems allows for a resonant virtual energy coupling between the two bodies (experiments on Cs/sapphire) - followed by demonstrations of long-range dissipative coupling (of the FRET type) between surface-polaritons and atomic systems. Recent works include spectroscopy/dynamics of gas atoms in nanometre vapour cell - with the first demonstration of coherent Dicke narrowing in the optical range, the exploration of vW forces in an unexplored distance range (20-100nm). The symmetry breaking character of atom-surface interactions was shown in surface/metastable beam collisions, where the anisotropic (quadrupolar) part of the vW interaction produces an exo-energetic metastability transfer between two different metastable states of rare gases. Extension to vW-induced transitions between Zeeman sublevels has opened the way to novel angle-tuneable atomic beam splitters and new approaches in matter wave interferometry (Fresnel atom interferometer, Schlieren-type atom nanoscope). This work extends now to atom-nanobody interactions and hybrid optical systems. Other recent interests are in matter-wave optics (as compared to light optics): non-diffracting atom nano-waves (similar to Fresnel beams in optics), negative-index media for atom optics and their applications.
