On May 23-25, 2021, the 2021 China Laser Technology and Industry Development Conference will be held in Changsha. The conference was hosted by the Chinese Optical Engineering Society, Hunan Provincial Department of Science and Technology, Hunan Science and Technology Association, and organized by the Laser Technology Expert Working Committee of the Chinese Optical Engineering Society, the Institute of Semiconductors of the Chinese Academy of Sciences, Tsinghua University, and co-organized by the Hunan Optical Society. The conference invited many domestic and foreign experts and scholars in the field of laser technology to participate, and carried out 5 keynote reports and more than 200 expert reports. Activities include technical exchanges, industrial development forums, results display docking, project roadshows and other activities, bringing together more than 100 industry experts, entrepreneurs, well-known consulting institutions, investment and financing institutions, and cooperative media. The outstanding achievements, technologies and products of various enterprises, scientific research institutes and universities in the laser industry will participate in the conference exchange and product display. The organizing committee also invited aerospace manufacturing, intelligent manufacturing, precision manufacturing, electronics/semiconductor industry, display, aerospace, laser additive manufacturing (3D printing), defense and military industry and other application departments to attend the meeting and communicate together. The organizing committee is committed to organically combining conference exchanges and industrial docking, and work together to create a high-standard and high-level advanced laser manufacturing industry application event. Dean Ye Yunxia and graduate student Zhao Yu attended the conference as a representative of the Institute of Micro-Nano Optoelectronics and Terahertz Technology.

      The paper submitted by Zhao Yu of Jiangsu University was selected as an excellent conference paper, and a report titled "Ultrafast laser preparation and terahertz modulation performance of silicon-based silver film microstructure array" was presented at the venue, introducing the micro-nano optoelectronics and terahertz research of Jiangsu University The research progress of the institute in the field of ultrafast laser preparation of terahertz devices, which focuses on the use of ultrafast lasers to prepare ultrasurface sensors, absorbers, filters, etc., and the application of ultrafast laser processing in micro-nano manufacturing The potential was prospected.

      In this conference, graduate student Zhao Yu conducted in-depth exchanges with participating experts and discussed their experience in laser micro-nano processing, which greatly expanded his academic vision. At the same time, it expanded the influence of the Micro-Nano Optoelectronics and Terahertz Research Institute of Jiangsu University in the field of terahertz. At the same time, it also promoted the school-running characteristics of Jiangsu University of "agriculture in industry and agriculture in industry".
