. In 1951 for work done at MIT, Brossel received his PhD in Paris under Kastler with a thesis on the application of double resonance methods (developed by Kastler and him) to the study of the excited states of
Hg. After completing his PhD, Brossel was attaché des recherches and then Maître de Recherches at
CNRS. In 1955 he became a professor at the Faculté des Sciences in Paris (and later a professor at the
University of Pierre and Marie Curie (Universitie Paris VI)). From 1973 to 1985 he was Director of the Physics Faculty of ENS. In 1985 he retired and went to the University of Paris.
Brossel is known for his work on
optical pumping with Alfred Kastler, with whom he founded in 1951 the spectroscopic laboratory at ENS (Laboratoire de Spectroscopie Hertzienne), which now is called the
Laboratoire Kastler-Brossel. Brossel was the co-director and then in 1972 after Kastler's resignation the director.
In his hometown of Périgueux a square is named after him.
In 1960 Brossel won the
