  Simulating photo-dissociation processes is a challenging task when the number
of states involved is significantly large. We present an ab-initio quantum
model for strong field photo-dissociation processes which incorporates
rotational dynamics. The computational complexity was reduced by employing the
random phase thermal wavefunction method. The simulation outcome are analogous
to experimental observable, such as the momentum angular distribution of the
photo-fragments. We studied the convergence of these observables at two field
intensities. The simulation method can be applied to wide-ranging time-domain
spectroscopy at experimental conditions far beyond the reach of accurate direct
numerical methods.
