Paper Abstract

The absorption characteristic and nonvolatile holographic storage are investigated for the first time in Ce and Ru codoped LiNbO3 crystals in this paper. The absorption spectra examination shows that there is a good optical transmission in the blue and violet wavelength range in the as-grown and oxidized samples. An absorption peak around 530nm induced by Ru can be found. A photochromic effect is observed through UV illumination experiment. Nonvolatile holographic recording is performed with different sensitizing and recording wavelength strategies. The results show that the highest recording sensitivity (0.050cm/J) and dynamic range (2.7 cm-1) can be obtained with 514nm recording and 405nm sensitizing.
