Abstract

A nominally undoped LiNbO3 crystal with a slightly broadened absorption edge is used to study beam coupling effects in the UV at 351 nm. At this wavelength the crystal exhibits a diffusion-dominated charge transport mechanism, which allows steady state beam amplification of up to 700 times, comparable to BaTiO3 in the visible. The used crystal material was characterized by an absorption coefficient α=2.68 cm−1 at 351 nm and a maximal gain coefficient Г=13.94 cm−1. This high gain value in the UV can be attributed to a hole diffusion-dominated charge transport mechanism together with a low bulk photovoltaic effect. We measured photovoltaic fields of the order of 550 V/cm.
