MgO:LiNBO3

The biggest determination of pure lithium niobate crystals is their low laser damage resistance threshold. When 5mol% MgO is doped, the laser damage resistance threshold of the grown MgO: LN crystal can be increased by 1-2 orders of magnitude. The OH – absorption peak shifts to 3535cm-1, the UV absorption edge shifts to 310nm, and the polarization reversal voltage decreases from 21KV/mm to below 6KV/mm. These changes greatly expand the application range of LN crystals.
