Abstract
A coupled equations approach is used to calculate the probabilities of photophysical processes in the ten photon absorption spectrum of H2 at wavelength λ= 532 nm. At high intensities, i.e., I > 1010 W/cm2, it is shown that above threshold photodissociation (ATPD) occurs readily in the B 1Σ+u state of H2 and in X 2 Σg+ of H+2. Laser-induced avoided crossings between the dressed B and F electronic potentials of H2 and also between the dressed X and A potentials of H+2 result in anomalous proton yields at intensities above 1011 W/cm2. The vibronic structure of the dressed X 2Σ+g potential of H+2 appears in all photodissociation yields as laser-induced resonances with intensity dependent line widths
