Holographic Photosensitivity Intensity Dependence of Azobenzene Molecular and Chalcogenide Glassy Films

Abstract:

Photosensitivity light intensity dependence of holographic grating recording in three azobenzene molecular glassy films (denoted as WE-3, ZWK-3, ZWK-2TB) and in one chalcogenide glassy film As₄₀S₁₅Se₄₅ (As-S-Se) has been experimentally studied in the intensity range from 0.0034 to 1.13 W/cm² at 633 nm. It is found that photosensitivity increases when recording light intensity is increased. The physical reasons are discussed and a simple mathematical model is given explaining the obtained results.
