Abstract

Angular-multiplexed hologram recording in iron-doped lithium niobate crystals was carried out with near-infrared light. An incremental recording schedule with active phase locking of the light pattern onto the hologram was used. Continuous and reproducible recording of holograms of equal efficiency was achieved, and a hologram multiplexing number, M/#=2, for a 5-mm-thick crystal was obtained at a 760-nm wavelength of light.

Diffraction efficiency η of hologram 5 versus recording time t for incremental recording of 10 holograms by active phase locking. The diffraction efficiency increases during recording of hologram 5 and decreases during recording of the other holograms. The doping concentration of the LiNbO3 crystal with Fe2O3 and the Fe2+/Fe3+ concentration ratio are shown. The solid curves are guides to the eye.
