Recently, a joint project entitled “Key Technologies of 100-watt Ultraviolet (UV) Picosecond/Nanosecond Lasers and Series of Intelligent Manufacturing Equipment” was awarded with the first prize of 2021 Guangdong Scientific & Technological Progress Award. Led by Prof. Ruan Shuangchen, president of SZTU, the project was jointly completed by a team formed by researchers from Shenzhen University (SZU) and Shenzhen Technology University (SZTU), together with Han’s Laser Technology Industry Group Co., Ltd. and CASTECH Inc. The other project members from SZTU are Wu Xu, Du Chenlin, Ouyang Deqin, Chen Yewang.

High-power and long-life UV lasers and its intelligent manufacturing equipment are vital for the precision processing of consumer electronics and semiconductors. After years of independent research, the project team has broken through the technical bottleneck in improving the efficiency and lifespan of UV lasers and extended the single-point lifespan of a crystal to over 8000 hours. Meanwhile, through the fiber-solid hybrid amplification technology, the team has solved the engineering and technical problems of UV lasers, and thereby developed the 100-watt UV picosecond/nanosecond lasers as well as UV laser intelligent manufacturing equipment for metal coating removal, multilayer and irregularly shaped circuit board processing, and advanced semiconductor wafer processing respectively.

The project has been granted 20 authorized invention patents, 32 utility model patents, 5 software copyrights and 2 enterprise standard certificates, with 16 papers published. It also won the first prize of Shenzhen Scientific & Technological Progress Award and was the only Asian project shortlisted for the Prism Award in 2017. More than 50 types of the invented laser equipment have been sold at home and abroad and widely used by many well-known enterprises. The achievements have made significant contributions to the technological development in laser precision manufacturing industry and enhanced the international competitiveness of laser manufacturing technology.
