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 3 crystal. The diffraction efficiency and sensitivity of the recording process at all wavelengths are increased by u
