Abstract

In this paper, the two-center recording with 633nm recording and 465nm sensitizing is performed in doubly-doped LiNbO₃:Fe:Ru and LiNbO₃:Ce:Ru crystals, respectively. The investigation for transmission spectra shows that the better transmission can be found from 400nm to 700nm in LiNbO₃:Ce:Ru crystals. Performance measures, such as diffraction efficiency, recording sensitivity, are calculated and compared according to the time evolution curves of diffraction efficiency. The results show that the high recording sensitivity and dynamic range can be obtained in LiNbO₃:Fe:Ru crystal. The scattering noise in LiNbO₃:Ce:Ru and LiNbO₃:Fe:Ru is investigated, the results show that the lower noise can be observed in LiNbO₃:Ce:Ru crystal.
