The laser heated pedestal crystal growth furnace (LHPG) produced by the company is a crucible free single crystal fiber growth process developed on the basis of the pull-up method crystal growth, using laser as the heat source. Due to its local melting characteristics, it can also be called floating zone melting crystal growth.
Laser heated pedestal crystal growth (LHPG) has unique advantages such as no crucible, no pollution, large temperature gradient, fast growth rate, and suitability for growing high-quality crystals with high melting points.
Product features:
·The system has multiple laser beams, and the laser power can be adjusted as needed
·High temperatures can reach over 2800 ℃
·The crystal pulling speed and rotation speed are precisely adjustable, and the pulling stroke is 140mm
·Can pass through various high-purity gas atmospheres such as argon and oxygen, or mixed gas atmospheres
·The pressure can reach 1.5 Bar
·The vacuum degree can reach 1X10-4mBar
·Real time observation of the entire process using CCD cameras, and real-time monitoring of temperature using non-contact infrared pyrometers
