Quantum-chemical methods are applied to calculate fluorescence photoresponses, constants for rates of the radiation decay, internal and intercombinational conversions (into triplet states), sections in channels of the ultimate amplification and the pumping-induced reabsorption. Taking into account that within the ultraviolet spectrum region in excited multiatom molecules there are inevitable multi-photon processes of deactivation of the excess excitation energy being reserved, the mandatory estimation of the ultimate leading edge duration of a pumping pulse is required while examining properties of an optical quantum generator.
