Coherent Light-Atom Interaction: From semi-classical to quantum


Several coherence spectroscopy effects are well described by the interaction of a classical field with a quantized atomic system. I review experiments on these effects, such EIT and EIA, carried in our laboratory and applications to light storage, metrology and the study of atoms under strong confinement. Later, I address recent experiments in which coherent light atom interaction results in light squeezing, a fully quantum state of the field.
