Kastler went to the Lycée Bartholdi in Colmar, Alsace, and entered at the Ecole Normale Supérieure in Paris in 1921. After his studies, in 1926 he first begun teaching physics in Lycée of Mulhouse, and then taught at the university of Bordeaux, where he became a university professor until 1941. Georges Bruhat asked him to come back at the Ecole Normale Supérieure, where he finally obtained a chair in 1952.
In link with Jean Brossel, he searched on quantum mechanics, interaction beetween light and atoms, spectroscopy. Kastler, working on combination of optical resonance and magnetic resonance, used the technique of "optical pumping". Those works led to complete the theory of lasers and masers.
He won the Nobel Prize in 1966 "for the discovery and development of optical methods for studying Hertzian resonances in atoms"
