Prof. Valentin Petrov, currently working in Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy, Germany, visited Fujian Institute of Research on the Structure of Matter (FJIRSM) on August 15th, 2019. While staying at FJIRSM, Prof. Valentin Petrov delivered a lecture entitled “Passively mode-locked 2-micron bulk solid-state lasers based on Tm- and Ho-doped materials”, and carried out detailed discussion with the researchers at FJIRSM.

Prof. Valentin Petrov received his M.Sc. degree in nuclear physics in 1983, and his Ph.D. degree in optical physics, for work on mode-locked dye lasers, from the Friedrich-Schiller-University, Jena, Germany, in 1988. He worked as an Assistant Professor at the Quantum Electronics Department, Faculty of Physics, University of Sofia, Bulgaria, from 1988 to 1991. After a one year Post. Doc. research visit to the University of Regensburg, Germany, he joined Max-Born-Institute for Nonlinear Optics and Ultrafast Spectroscopy (MBI) in Berlin, Germany, in 1992. Further research stays abroad include a JRDC STA fellowship at RIKEN (Japan) in 1996-1997 and a visiting professorship to the Université Joseph Fourier (Grenoble, France) in 2014. His research interests include ultrashort light pulses, laser physics, nonlinear optics, and optical materials. He has co-authored about 520 papers in peer-reviewed scientific journals and more than 600 conference presentations. His h-index is 61 with >13000 total citations (Google Scholar).
