Abstract
In recent experiments of M. Gruneisen et al., the possibility was shown to record the so-called 'blazed' dynamic holograms in optically addressed liquid crystal spatial light modulator (OA LC SLMs). In such holograms the phase retardation distribution across the holographic fringe has a saw-like shape (asymmetrical triangle). Such holograms can provide a very high (in a limit - nearly 100%) diffraction efficiency. In previous experiments such 'blazed' holograms were recorded with the use of digital computer methods. We propose a novel, analogous an completely optical approach to the record of such holograms. One can record a saw-like profile of phase retardation in an OA SLM, placed into the nonlinear interferometer. In such interferometer the probe wave reads out the phase retardation in SLM, interferes with reference wave, and the phase retardation in the said SLM is controlled by their interference pattern. The results of the direct numerical simulation of the system show that by this method can be formed the saw-like grating, providing nearly 100% diffraction efficiency. Presented is the analysis of the system dynamics and stability.
