✦ Synopsis

We apply to two-photon resonant ionization of Cs via resonant dissociative states of Cs2 the technique of transition probability saturation. Our measurements are perfotmed both with linear and circular polarization. Independently of the Cs2 density, they provide the first absolute determination of the photodissociation cross section averaged over the molecular states, a,r,= (7.3+ 1.1 )X lo-" cm2 at 550 nm, and of the photoionization cross section of the product atoms in the 5Ds,, state, Ui,=(3 3kO 5)X10-"cm'.
