High Homogeneity of Magnesium Doped LiNbO<sub>3</sub> Crystals Grown by Bridgman Method

A series of LiNbO<sub>3</sub> crystals doped with various MgO concentrations (0, 3%, and 5 mol%) was simultaneously grown in one furnace by the modified vertical Bridgman method. The wet chemistry method was used to prepare the polycrystalline powders, and the growth conditions were opti...
