Research output: Chapter in Book/Report/Conference proceedingConference contribution


Femtosecond pulse mode-locked VECSELs have become a significant focus of research in the VECSEL community, with recent progress being made in several directions including power scaling. Power scaling advances in femtosecond VECSELs have included increasing the average power to over 5W [1], producing 3.3W average power with 400 fs pulses [2]. Here I report our recent work reducing the pulse duration of Watt-level VECSELs to 355 fs, and also developing approaches to reach sub-250-fs pulse durations using coherent broadening in photonic crystal fiber in the normal dispersion regime and a grating pulse compressor.
