Hung-Sheng Chiang, researcherHung-Sheng is currently a Researcher in the Department of Electrical and Computer Engineering. He has been working on building and characterizing passively phase-locked fiber laser arrays. He experimentally demonstrated Kramers-Kronig self-phasing in this laser architecture. Recently, his research is shifting from CW lasers towards pulsed lasers. He envisages a new class of pulsed lasers that are powerful enough to ignite nuclear fusion reactions or serve as the building blocks of next-generation particle accelerators. He completed his PhD degree in Physics in 2011 here at University of Minnesota Twin Cities. He specializes in condensed-matter physics. email: chia0078@umn.edu |

Erik Tilseth, graduate studentErik received his B.S. in Physics from the University of Minnesota in 2016, and is now a first-year Ph.D student in Electrical Engineering at the same institution. He is currently investigating phase shifts due to the Optical Kerr Effect in coherently-combined pulsed fiber lasers. This work builds on prior discoveries of Kramers-Kronig phase shifts in similar laser architectures. email: tilse006@umn.edu |
