Abstract

Single crystal of LiNbO 3 has been successfully grown by the Czochralski met hod in an air atmosphere with a r.f heating crystal growth sy stem namely Automatic Diameter Control Crystal Growth System (ADC-CGS). This paper reports on the effect of new thermal insulation on the growth process of LiNbO 3 single crystal. The effect of hot zone thermal ins ulation design was investigated. The conditions required to grow high quality LiNbO 3 single crystals are described. A set of crystal growth processes were conducted with the rotation rate of the seed at 15 rpm and the pulling rate at 2.0 mm/hr kept constant. All of the runs were grown along <104> orientation. To control the diameter of the crystal, we have to alt er the thermal environment inside the hot zone. In other words, during the crystal growth we have to i ncrease the control power to get smaller diameter and decrease the control power to get larg er diameter.
