Light absorption measurements of nominally undoped congruent lithium niobate crystals (CLN) as well as 5 mol% magnesium-oxide-doped lithium niobate (MgO:LN) crystals were performed in the light wavelength range of 350 to 800 nm. Absorption spectra re

Recent progress in periodic poling of magnesium-doped lithium niobate has made the material interesting for applications in second harmonic generation (SHG) of green light. The ternary phase diagram has been studied previously and a threshold composi

Eleven lithium niobate crystals were grown using the Czochralski method from melts deviating from the congruent melting composition and the resulting axial variation of the crystal composition was analyzed using Curie temperature measurements. The we

Advances in Optical Materials.
Absorption measurements in 5 mol. % MgO-doped lithium niobate crystals (optical grade) are presented. Measurements reveal that optical losses in these crystals are mainly caused by H, Fe, Cu, Ni, Cr, and Mn impurities.

Absorption measurements on 5 mol. % MgO-doped and undoped congruent lithium niobate (LiNbO(3)) crystals revealed absorption bands in the wavelength range of 2500-2800 nm, caused by incorporated hydrogen ions. High-temperature annealing was applied to

This contribution deals with light absorption and temperature-change-induced optical damage due to the pyroelectric effect in undoped and magnesium-doped lithium niobate crystals. This effect is different from the photorefractive optical damage.
