Title: Advanced ultrafast laser sources harnessing fiber-optic nonlinearities

Abstract:

Propagation of strong femtosecond pulses inside an optical fiber causes fiber-optic nonlinearities and results in numerous interesting nonlinear optical phenomena. We employ fiber-optic nonlinearities to improve the performance of ultrafast fiber lasers. The resulting novel ultrafast laser sources promise important applications in multiphotonmicroscopy imaging and high-power mid-infrared frequency combs.

Biography:

Dr. Guoqing Chang graduated with both Bachelor and Master degrees from Electronics Engineering department of Tsinghua University and Ph.D. degree in Electrical Engineering from the Center for Ultrafast Optical Science at the University of Michigan. After staying at the University of Michigan as a postdoctoral research fellow for about one year, he joined the Research Laboratory of Electronics at MIT as a postdoctoral research associate. In August 2012, he moved to the Center for free electron laser (CFEL) at Hamburg (Germany) as the head of the Helmholtz Young investigator group “Ultrafast Laser Optics and Coherent Microscopy”. He was granted tenure in December 2016. Recently he joined the Institute of Physics, Chinese Academy of Sciences.
