duanpic1 Lingze Duan, Associate Professor (Ph.D, University of Maryland)

Joining the Physics Department of UAH in 2007, Dr. Lingze Duan has been conducting research in the areas of femtosecond frequency combs, atmospheric optics, fiber optics, fundamental thermal noises in one-dimensional systems, and optical probing of intergalactic plasma. He is a recipient of the National Science Foundation CAREER Award in 2013 for his proposed research in ultrafast nanophotonics. Dr. Duan's past research includes developing ultra-stable diode lasers using high-Q passive optical cavities (2004-2007, Penn State University), studying direct detection of the carrier-envelope phase of femtosecond pulses with an octave-spanning Ti:Sapphire laser (2002-2004, MIT), and developing wavelength-tunable mode-locked fiber lasers (1998-2002, University of Maryland). He has authored or co-authored over 40 refereed technical publications in leading optics and physics journals and conferences. See Curriculum Vitae for more information.
