Biography:

Zhiyi Wei obtained PhD from Xi’an institute of optics and fine mechanics, Chinese Academy of Sciences (CAS) in 1991. From 1991 to 1997, he was a postdoctoral researcher and associate professor in Sun Yat-Sen University. He joined in the Institute of Physics, CAS since 1997 and promoted as full professor in 1999 . During 1993 to 2002, he also worked at RAL in UK, the Chinese University of Hong Kong, the Hong Kong University of Science and Technology, University of Groningen in the Netherland and Advanced Institute of Science and Technology in Japan as a visiting scholar and postdoctoral scientist. During the long career on ultrafast laser technology and applications, he has published more than 300 peer review papers in Nature Photonics, Phys Rev Lett, Opt Lett etc. more than 70 invited talks in international conferences. As the first contributor, he won 1 national second award on technology invention and 3 ministry second awards on science and technology. He also accepted the award for young scientist by CAS in 2001, national talent young scientist fund in 2002, Hu Gangfu award for experimental physics in 2011. We is the committee member of IUPAP, Max-Planck Center for attosecond and X-ray Science and Asian committee on ultrahigh Intensity laser. In view of his major contributions on ultrafast and ultrahigh intensity femtosecond laser community, he was selected as OSA fellow in 2017.     



報告摘要:

超短激光脈沖作為激光科學與技術的重要研究内容,不僅改寫了許多光學研究的新紀錄,而且也推動着大量相關前沿研究的革命性進展和科學交叉。目前利用钛寶石激光啁啾脈沖放大技術(CPA),人們所能得到的激光峰值功率已達10拍瓦的量級,為加速器物理、高能物理、核物理等學科提供了新的研究手段。法國籍科學家 G.Mourou教授和他的學生D.Strickland 副教授因發明CPA技術而共享了2018年一半的諾貝爾物理獎。此外通過飛秒激光與物質相互作用産生的高次諧波,人們在極紫外波段得到了短于50阿秒的最短脈沖世界紀錄。本報告将結合報告人研究團隊在超快超強激光研究方面的新進展,綜述介紹利用該激光已取得并可能進一步開展的前沿應用。


Abstract: 

Ultrafast intense laser has been recognized as one of the most promised field in laser science, it has not only broken many new world record in optical technology, but also made the remarkable progresses in frontier applications and disciplines cross. Up to now, ultra-intense laser with peak power up to 10 PW has been reported based on the technology chirped pulse amplification (CPA), which enable us the cutting edge platforms for particular acceleration, high energy physics etc., In 2018, G. Mourou and D. Strickland won the Noble Prize for the invention of CPA.  In addition to, the shortest laser pulse of shorter than 50as has been generated at the wavelength in XUV range based on the high harmonic generation (HHG)driven by femtosecond intense laser pulse. In this talk, I will introduce the recent development on ultrafast intense laser and new progresses in my group. The further development and potential applications will be also prospected.
