Innovation point: Through the crystal growth machine's modification in rotating and lifting system, the stability of crystal growth interface and growth rate become higher. Also the defects caused by the influence of crystal rotating and rising disturbance on the solid-liquid interface during the crystal growth process are reduced. we create simulation of crystal growth system and can design crystal shape. The computer chip control the changing of crystal shape according to crystal growth status, through the processing of precision sensor signals. The ultra low gradient interface growth temperature field we self-designed make the quality of optical crystals much better.
