摘要
This paper investigates the photorefractive properties of iron doped lithium niobate with different [Li]/[Nb] ratios.The experimental results show two photorefractive centres for iron doped near-stoichiometric lithium niobate crystal.Besides Fe 2+ and Fe 3+ ions,small polarons and bipolarons are considered as another photoactive centre.
