Résumé
Abstract

Cet article présente une revue des expériences de spectroscopie à deux photons sans effet Doppler, réalisées depuis le début des années 1970 jusqu'à la fin des années 1990. La méthode de spectroscopie à deux photons sans élargissement Doppler a d'abord été testée sur l'atome de sodium, puis elle a été utilisée extensivement pour étudier l'hydrogène atomique et mesurer la constante de Rydberg et les déplacements de Lamb.

This paper gives a review of the Doppler-free two-photon experiments performed since the beginning of the 1970s until the end of the 1990s. The Doppler-free two-photon method was first tested on the sodium atom, then used extensively to study the hydrogen atom and measure the Rydberg constant and the Lamb shifts.
