    Location: 
    Meinel 307
    Description: 

    Khanh Kieu will present "Generation of Ultrafast Optical Pulses and Applications."

    Abstract(s): 

    Ultrafast laser pulses (picosecond and femtosecond duration) are important tools in modern science and technology with significant impacts in different fields. In this talk, I will discuss about our research activities in the development of compact ultrafast fiber lasers and their uses in applications such as supercontinuum generation, nonlinear spectroscopy, all optical switching and nonlinear imaging. I will show our latest results in nonlinear optical microscopy of graphene, electrical integrated circuits and photonic devices on a chip. I will spend some time presenting our new findings in nonlinear bio-imaging: Our compact ultrafast fiber lasers give us the opportunity to look deep into different biological samples and have enabled us to see the hidden nonlinear microscopic world with high resolution, in 3-D.

    Speaker Bio(s): 

    Khanh Kieu became an assistant professor at the University of Arizona College of Optical Sciences in August 2012. He received a B.S. in applied physics in 2002 and an M.S. in laser technologies in 2004 from the St. Petersburg State University of Information Technologies, Mechanics and Optics (Russia). His research was focused mainly on laser material processing and laser matter interactions. Kieu received his Ph.D. in optical sciences from OSC in 2007. After graduation, he was a postdoctoral researcher at Cornell University, where he conducted research in high-power ultrafast fiber lasers before returning to the College of Optical Sciences in 2009 as research faculty. He has authored and co-authored more than 35 journal articles, three U.S. patents and numerous conference talks and proceedings.
