Abstract
We calculate the influence of thermal patterns and pyroelectric fields on photorefractive holographic recording in terms of a one center cha rge transport model, taking into account diffusion, photovoltaic curre nt and space charge limitation. At pulse laser intensities the pyroele ctric effect can enhance the holographic sensitivity and the saturatio n value of refractive index changes significantly.
