Paper Abstract

Intrinsic two-photon excitation and absorption processes have been studied in Al2O3, YAP and YAG crystals in the temperature interval 80 - 300 K. The comparison with the one-photon processes in the same region of energies of electron excitations has shown, that different electron excitations are responsible for the absorption in both these cases. Specific relaxation features of electron excitations are discussed in the frame of model taking into account non- bonding states of oxygen.
