Abstract
A bismuth and magnesium co-doped lithium niobate crystal includes LiCO, NbO, BiOand MgO, wherein the molar ratio of [Li] and [Nb] is 0.90-1.00, the molar percentage of BiOin the mixture is 0.25-0.80%, and the molar percentage of MgO in the mixture is 3.0-7.0%. The bismuth and magnesium co-doped lithium niobate crystal has enhanced photorefraction, improved photorefractive sensitivity, shortened holographic grating saturation writing time, and the photorefractive diffraction efficiency can reach up to 17%. The response time is only 170 ms, when the holographic storage experiment is carried out using 488 nm continuous laser. Therefore, this crystal can be used in the field of holographic imaging.
