Abstract
We report on nonvolatile holographic recording in Ru doped LiNbO3 crystal, to our knowledge, for the first time. Irradiation of the blue light induces the absorption change in the spectral range up to 650 nm. The nonvolatile hologram can be recorded at the recording wavelength of 632.8 nm when the blue light is simultaneously incident on the crystal. The diffraction efficiency of the nonvolatile hologram is about 1 % at the extraordinary polarization.
