Picosecond VECSELs achieve high average output powers of up to 2.1 W and pulse repetition rates of up to 50 GHz using semiconductor saturable absorber mirrors (SESAMs) for modelocking. The shortest pulse duration generated by a VECSEL is 260 fs, which is achieved at 15 mW average output power. We show for the first time a passively modelocked VECSEL, where the gain and the absorber are both entirely...
The authors demonstrate up to 4.35 W output power from a Stranski-Krastanow grown quantum dot semiconductor disk laser (SK-QD SDL), representing a 15 times increase in power from the previous published maximum power in the work of Germann et al. (2008), and the first multi-Watt output from any QD SDL. The experimental demonstration of a multi-Watt power level continuous wave operation of QD based...
