Patrick Dupré,


University of Burgundy



The author has a long experience in high resolution spectroscopy, building up setups in different laboratories and in different countries. He faced diverse kinds of spectroscopy covering multiple spectral ranges. He had to analyze all sorts of spectra requiring for calculating effective molecular Hamiltonians. He has a background in high-sensitive techniques involving high-finesse optical cavity, targeting from diatomic to large polyatomic molecules, in cell and supersonic jet expansions. He recently made a lot of efforts to understand the saturated absorption in different molecular systems involving hyperfine structures. This involves ab-initio molecular calculations, and modeling 3-energy level systems coupled by 2 counter-propagating beams under saturated absorption. Furthermore, he considered the saturated absorption involving non wave-planes, i.e., systems with a finite time of interaction.
