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.
