Title: STABILIZED PHOTOREFRACTIVE MODULATION RECORDING BEYOND 100-PERCENT DIFFRACTION EFFICIENCY IN LINBO(3)-FE CRYSTALS
Author: FRESCHI, AA
FREJLICH, J
Abstract: A small photochromic grating is selectively and continuously detected from a much larger photorefractive modulation in Fe-doped LiNbO3 crystals in a two-wave mixing experiment. The recording setup is actively fixed to either the photochromic or the photorefractive grating. In the former case a photorefractive modulation largely exceeding the value required for 100% diffraction efficiency is achieved. In the latter case this modulation is limited to 100%. Experimental results are in good agreement with the theoretical model.
