Some new results of Raman spectra of Al2O3:Ti3+ crystals are reported. It was experimentally found that Al2O3 crystals doped with Ti3+ ions "would increase the intensity of two Raman peaks which correspond to external vibrations of eigenmodes respectively. Based on the model of photon-electron coupling, an explanation to this phenomenon is given.
