Abstract
The quasi-level avoided crossing in the laser-induced continuum structures is traced theoretically as a function of the intensities of the strong laser fields. We study, in the adiabatic regime, the effects induced by two strong laser fields in the continuum of the H atom. In the photoionization spectra of the probe field from the ground Is state, the coupling to the 2s, 5s, 5d, and 5g states is considered. Under certain conditions, the quasi-levels cross and the S-matrix has a double pole related to branch point in the complex plane. Although the number of these branch points is very small, they determine the dynamics of the system in a decisive manner.
