Seminar: "Development on high-contrast PW Ti:sapphire laser system" by Zhiyi Wei
Friday, October 04, 2013 12:00 PM to 1:00 PM
CREOL Room 102

The progress of chirped-pulse amplification (CPA) technology has provided great opportunities for researches on laser-matter interactions with relativistic intensity. To date, several laser systems with peak power up to Petawatt (PW) have been realized with different schemes in the world. For laser-matter interaction experiments at such intense level, the contrast is required as high as 10-10 to prevent pre-plasma dynamics. In this presentation, we will present the recent progresses of XL-III laser facility at Institute of Physics, Chinese Academy of Science. Laser power up to 1.16PW with contrast ratio reached to 10-10 was obtained. 

Prof Dr. Zhiyi Wei is the group leader of ultrafast laser Group and the director of Joint Laboratory of Advanced Technology in Measurements at Institute of Physics, Chinese Academy of Sciences. His research interests focus on the generation, amplification and application of ultrafast laser pulse. He received many awards for contributions to laser science and technology, which include a Second Class National Natural Science Awards, Young Scientist Award of CAS, and Gangfu Hu Physics prize.

        Prof Wei earned a Ph.D Degree from Xian Institute of Optics and Precision Mechanics, CAS in 1991. After two years postdoctoral fellow at Sun Yat-Sen University in China, he conducted research at the Rutherford Appleton Lab in UK, the Chinese University of Hong Kong, the Hong Kong University of Science and Technology, University of Groningen in the Netherland as a visiting scholar from May 1993 to March 1997. In Holland he and his colleagues broke the world record at that time for generate sub-5fs laser pulse. From 2000 to 2002, he was a NEDO fellowship researcher at the Institute of Advanced Industrial Science and Technology (AIST) in Japan. He is a member of C2 (Symbol and Constants) sub-committee of International Union of Pure and Applied Physics (IUPAP), an international advisory member of the journal of Measurement Science and Technology, a member of the Max-Planck Center for attosecond science.
