【Abstract】 Optical transmission spectra and the gain of photorefractive effect two-wave mixing were investigated in double-doped LiNbO 3(Ce:Fe,Ce:Mn,Mn:Fe).The experimental results show that the optical transmission spectra range and two-wave mixing gains are smaller in the high doped LiNbO 3 crystals.The properties of photorefractive effect in double-doped LiNbO 3 samples are not superior to those of doped Fe samples.Photorefractive effect resistant is shown in double-doped samples.更多还原
