HL: Fachverband Halbleiterphysik

HL 3: Focus Session: VECSEL

HL 3.1: Invited Talk

Monday, March 26, 2012, 09:30–10:00, ER 164

Recent advances in ultrafast VECSELs and MIXSELs — •Thomas Südmeyer^1,2, Valentin J. Wittwer², Oliver D. Sieber², Mario Mangold², Martin Hoffmann², Yohan Barbarin², Matthias Christoph Golling², and Ursula Keller² — ¹ETH Zurich, Switzerland — ²University of Neuchatel, Switzerland

Ultrafast VECSELs and MIXELS are promising cost-efficient, reliable, and compact ltrafast laser sources. Modelocked VECSELs can achieve low-noise operation and >1 W in sub-picosecond pulses have been reported. The highest average powers are obtained from MIXSELs, VECSELs with integrated saturable absorber. Recent developments in these devices are reported.
