Recording of holographic gratings and their coherent self-enhancement in an a-As<sub>2</sub>S<sub>3</sub> film with a minimum light intensity modulation
Abstract:The holographic grating recording efficiency and the coherent self-enhancement efficiency of gratings are experimentally studied depending on the recording light interference fringe visibility in an a-As 2 S 3 chalcogenide film in order to find the minimum visibility. The minimum fringe visibility M min = 3.6×10 -4 is found, which is determined by the scattered light background. In this case the maximal diffraction efficiency η max = 0.05% and the maximal self-enhancement factor ξ max = 5.0, compared to η max … Show more
