摘要: The changes in optical properties of bulk LiNbO3 crystals were investigated depending on the diffusion depth. For this purpose samples isochronously annealed hydrogen, subsequently reduced air. investigations held different crystallographic directions. experimentally determined distribution depth-dependent additional absorption was approximated basing oxygen vacancies model and solution differential equations set describing quasichemical reaction bipolarons formation due to loss crystal.
