Interference stabilization of diatomic molecules with respect to their photodissociation by a strong laser field is considered. Multiple strong-field-induced Raman-type transitions between vibrational levels of the ground electronic state are taken into account. For the molecular ion H2+ matrix elements of these transitions are calculated, the arising equations are solved numerically, and the time-dependent probability amplitudes to find a molecule at ground-electronic-state vibrational levels are found. In a stationary formulation, complex quasienergies are found and analyzed. At some specific values of the light frequency some quasienergy zones are shown to narrow with growing light intensity, and this effect is related directly to the field-induced stabilization. In solution of the initial-value problem, the total probability Of photodissociation per pulse is shown to decrease its growth with growing peak light intensity. Investigation of frequency-dependence of the photodissociation yield is used to determine stabilization conditions and to clarify the physical origin of the effect.
