Paper Abstract

A scheme of using carbon-dioxide laser beams to thermally fix layers of photorefractive holograms to implement a solid-state optical system in a single block of LiNbO3 crystal is suggested. In this paper, a modified gamma network is adapted to demonstrate, and a stage of such a network is constructed in a block of crystal. To limit the heating region with the shape similar to the heating beam, two carbon-dioxide laser beams of narrow width are used to laterally illuminate a layer of crystal, and additional absorbers are attached on the crystal surfaces outside the heating region to guide the heating flows. Analytical discussion based on the heat- transfer equations and the proof-of-principle experimental result are given. It can be thus seen that it is possible to package an optical system into a miniaturized single-block of photorefractive crystal.
