We studied the influence of field properties on the angular distribution of the outgoing fragments in the laboratory-fixed axis, defined by the field polarization. An ab initio model of strong-field photodissociation of diatomic molecules was developed. Simulating the full process is obstructed by a number of numerical complexities. For example, angular momentum algebra and the initial thermal state. As a result, the Hilbert space size increases tremendously with temperature. Final state analysis is performed after a carefully designed absorbing boundary condition.
