We study two-color photoionization of helium in the region of the 3s3d D-1 autoionizing state with resonant excitation of the intermediate 2s2p P-1 autoionizing state. We show that the corresponding time-dependent Schrodinger equation may be solved by expanding the total wave function on a few complex energy states. Perimetric coordinates are used to describe correlation effects accurately. Populations at the end of the interaction as well as photoionization probabilities are studied as a function of the laser pulse duration acid both frequencies. Our calculations show that many continua play a crucial role at high intensities. [S1050-2947(99)06308-8].
