Abstract

We report the use of self-stabilized holographic recording techniques for the recording of a hologram in a photorefractive iron-doped lithium niobate crystal at moderately high temperature and simultaneously compensating it by allowing the diffusion of positively charged hydrogen ions After white-light development an efficient fixed grating is obtained even for reduced samples A fixed grating with diffraction efficiency is obtained in these conditions in a reduced crystal but higher values are possible
