20 kW laser system for producing high purity crystals

Press Release /

High-purity semiconductor crystals are required for power electronics in electric cars or in photovoltaics. When such crystals reach a diameter of 2 inches, they become relevant for industrial applications. Researchers from Japan and Germany have now developed a method to produce such crystals using a laser-based process, and without a crucible. The team at the Fraunhofer Institute for Laser Technology ILT in Aachen has developed a process-adapted optical system for use with a 20 kW laser.
