Langasite Crystals Growth with Quality Factor Q, That Exceeds the Q of Quartz, and Which are Suitable for High-Precision Resonators.
Abstract
Processes of langasite crystal growth are considered. Distribution of temperature fields, heat assembly design, pulling and rotation rates are optimized. Composition of charge, impurity content and technology of its manufacture have been studied. Influence of annealing regimes and gaseous medium on crystal quality are discussed. The main defect types encountering in crystals are identified. Langasite resonator at 5 MHz, 3rd overtone has been developed.
