    Harnessing ultrashort optical pulses


    Ultrashort optical pulses have found important applications in material processing, precision measurements, time keeping, and multiphoton microscopy. In this presentation, I will discuss our research results in the development of compact fiber lasers that emit ultrashort optical pulses in the picosecond and femtosecond time scale. These compact lasers can now operate in a very wide wavelength range from deep UV to long-IR which will be important for their widespread use. In addition, some useful applications of ultrashort optical pulses that we are working on in our research group such as 2D materials characterization, multiphoton imaging of biological tissues and dual-comb spectroscopy will also be presented.

    Speaker Bio(s): 

    Dr. Khanh Kieu is an assistant professor at the University of Arizona, College of Optical Sciences. 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. Dr. Kieu received his Ph.D. in optical sciences from OSC in 2007. He was a postdoctoral researcher at Cornell University where he conducted research in high-power ultrafast fiber lasers. He has authored and co-authored more than 70 peer-reviewed journal articles, five issued U.S. patents and numerous conference talks and proceedings.
