Abstract

Time-dependent diffraction efficiency is measured during hologram formations in a dichromated gelatin film. It is observed that the refractive index modulation is strong nonlinear with exposure time. In order to explain the complicated hologram formation dynamics, we present a phenomenological model for photoinduced refractive index changes by assuming that two photochemical reaction centers are responsible for the hologram formations.
