| Abstract: | In this paper, for Mg(5mol %) : LiNbO3,Mg( 4 mol%):LiNbO3 and LiNbO3 crystals ,the photorefractive thresholds, the infrared transmission spectra, the efficiendes ofdouble-frequency and the temperatures of phase- matching have been measured. The stateof Mg(2 ) ions in Mg : LiNbO3 crystals and the photorefractive resistance enhanced mechanismhave been investigated too. |
