Abstract
Experiments on hologram recording in porous structure obtained by the sol-gel technology were performed. It was shown that holograms with a diffraction efficiency close to 100% can be obtained with the exposure of about 0.1 J/cm. A pronounced birefringence was observed in dry sam ples, but it diminished upon immersion in liquids. To explain this eff ect, a theoretical model was developed. It was shown that even a low a symmetry in pore structure leads to a pronounced birefringence.
