Abstract
Nonvolatile holograms were recorded by using a long wavelength of 633 nm (He-Ne laser) for recording and a short wavelength of 458 nm (Argon ion laser) for sensitizing in double doped LiNbO3:Cu:Ce crystals. The sensitizing light increases the recording sensitivity by a - bexp(-Is/c) and saturation behavior will appear with high enough intensity of sensitizing light. The recording light increases the slope of (eta) 1/2 as a function of time during the initial stages of hologram formation by sublinear Irx (x < 1) and thus the recording light decreases the recording sensitivity. The dependence of saturation diffraction efficiency on the intensities of the recording and sensitizing light shows that there is a maximum dynamic range of the recording process.
