Laser type (standard type/high pressure type)
Optical Floating Zone Furnaces
Our laser FZ furnaces use localized heating to minimize thermal effects outside the melted area, enabling the crystallization of a wide variety of materials. Real-time monitoring using Infrared thermometer (Pyrometer) and video ensures stable and reproducible growth.

Product Introduction
Our laser single crystal growth furnaces use the laser floating zone (FZ) method, which minimizes the thermal impact on areas other than the molten area through localized heating using a sharp temperature gradient. It is also highly effective in crystallizing decomposed molten materials, which was difficult with conventional lamp heating methods. Furthermore, by incorporating a Infrared thermometer (Pyrometer) and real-time monitoring function using video, we have achieved a highly reproducible crystal growth process.
Uniform heating with multiple laser diodes
Multiple laser diodes, evenly spaced apart, heat the melting zone uniformly, minimizing temperature variations and improving interface smoothness and reproducibility.
Steep temperature gradients allow for decomposition-melting materials
The temperature gradient is steeper than lamp heating, enabling the growth of decomposition-melting materials such as BiFeO₃ and (La,Ba)₂CuO₄, which were previously difficult to grow using conventional methods.
Wide Growth Speed Range
Slow feed: 0.01 to 300 mm/h, fast feed: 1 to 150 mm/min. Flexible control from ultra-low to high speeds is possible, making it compatible with a variety of material.
Real-Time Process Monitoring
Continuously monitor temperatures and conditions with live monitoring using Infrared thermometer (Pyrometer) and video. The PC-based GUI provides high operability and flexible software updates and customization.
Temperature Gradient Measurement Using a Infrared thermometer (Pyrometer) (Standard Type)
Automatically measures the vertical temperature gradient to precisely monitor the condition of the crystal during growth.
Selectable High-Power Laser Modules (Standard Type)
Equipped with five 200 W modules as standard (1 kW total), with an option to upgrade to five 500 W modules (up to 2.5 kW total). Capable of processing ultra-high-temperature materials such as tungsten (melting point over 3400 °C).
Variable/Fixed Beam Angle Mechanism
The standard type features an adjustable beam angle between 0° and 30°. The high-pressure model has a fixed angle of 30°, making it compatible with high-pressure techniques such as the SCFZ method.
Crystal Growth Under Vacuum and High-Pressure Atmospheres
The standard model, when equipped with an optional vacuum pump, achieves high vacuum levels of 6.7 × 10⁻³ Pa or better, and supports crystal growth under high-pressure atmospheres up to 0.95 MPa. The high-pressure model allows crystal growth under pressures up to 15 MPa.
