Hydrothermal Growth of Emerald Laser Crystals

Emerald is an excellent tunable lasing medium. According to controlling seed orientation and using special nutrient separation quartz-seed stack-up technology, many plate and columnar emerald single crystals were hydrothermally grown in one autoclave at a time. Detected by absorption specta, microscope and laser experiment, the quality and characterization of the emerald crystals obtained are analogous to those of natural and other hydrothermal emeralds synthesized by other countries.
