Nonvolatile two-color holographic recording in Tm-doped near-stoichiometric LiNbO 3
(2005) In Optics Communications 248(1-3). p.89-96- Abstract
We have observed ultraviolet-induced visible absorption and performed two-color holographic recording at green, red, and near-infrared light in thulium doped near-stoichiometric LiNbO

Characteristics of recording in the visible are explained by a two-center model. Two-color recording in the near-infrared exhibits significant improvements of the fixed diffraction efficiency and the role of small polarons is discussed in the visible and near-infrared recording with ultraviolet sensitizing...
