A research group led by Prof. Sun Dunlu from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences, has successfully synthesized novel mid-infrared Ho,Pr:YAP and Er:YGGAG crystals using the Czchralski (Cz) method, and improved the continuous-wave laser performance of laser diode (LD) side-pumped Er:YSGG crystal through thermal bonding technology.
