The multiphoton dissociation branching ratios for H{sub 2}{sup +} and D{sub 2}{sup +} as a function of laser peak intensity and pulse length are investigated by solving the time-dependent Schroedinger equation in the Born-Oppenheimer approximation, neglecting nuclear rotation. An 800 nm laser pulse with peak intensities from 8x10{sup 9} W/cm{sup 2} to 10{sup 14} W/cm{sup 2} and pulse lengths from 5 to 7.5 fs is used. We also investigate the viability of identifying zero-, one-, two-, and three-photon processes based only on the nuclear kinetic energy release spectrum, and check these identifications with a rigorous Floquet-like method.
