Neodymium-doped yttrium aluminum garnet (Nd:YAG) which is one of the most popular laser crystals has been widely used in solid state laser. Nd: YAG crystals with the diameter of 80 mm are grown by Czochralski (CZ) method. The up-weighing automatic diameter control (ADC) system is used to obtain the good quality of large diameter Nd:YAG crystals. Four common defects of Nd:YAG crystals are analyzed by adjusting the growth parameters and optimizing the thermal environment. Perfect Nd:YAG crystal with diameter of 80mm and lengh of 350 mm has been obtained successfully in this work.
Keywords:Crystal growth; Crystal defects; Nd:YAG laser crystal; Large size
