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.
