摘要：

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