Xinyang LIU got his Bachelor of Science degree in 2016 from Qingdao University, China. With a physics background, he then entered Shandong University for his Master of Engineering degree while working on solid-state lasers. After three years’ research experience on solid-state lasers, he moved to Tampere University, Finland, for his Doctor of Science (Technology) degree. After completing his tasks on two European H2020 projects, i.e. building ultrafast fiber lasers for laser machining and bioimaging, he finished his doctoral period in 2024. Xinyang gained experience on both numerical simulation and experimental study of 1 μm Yb-doped and 1.7 μm- 2 μm Tm-doped ultrafast mode-locking fiber lasers during his doctoral period. Additionally, he proposed and realized, in numerical simulation, neural-network prediction of mode-locked fiber laser outputs from laser cavity parameters. Apart from doing research, he serves the scientific community as a reviewer for journals like Optics Letters, Optics Express, Chinese Optics Letters and High Power Laser Science and Engineering.
