One experiment with a three-photon Doppler-free transition is also described. Other experiments show the possibility of increasing the transition probability by using two lasers with slightly different wave lengths. Typical recordings of two-photon transitions are given they show line widths smaller than 4 MHz (on a Doppler width of 2000 MHz). A typical experimental set-up with a cw dye laser is described in detail. The problem of light shifts is also discussed. Calculations of the multiphotonic transition probability are summarized and their hypotheses specified: one deals with line shape and orders of magnitude in practical conditions. A generalization is made for multiphotonic transitions. The principle of the method is discussed: the Doppler broadening is suppressed in two-photon transitions if the atoms are irradiated by two laser beams travelling in opposite directions, because the Doppler shift in one wave cancels that in the other. We show theoretically and experimentally the possibilities of these transitions for numerous high-resolution spectroscopic studies. We describe atomic transitions where two or more photons are simultaneously absorbed by an atom or a molecule (without any intermediate resonant level).
