Abstract

We present our first flip-chip processed, modelocked InGaSb vertical external-cavity surface-emitting laser (VECSEL) in the 2-µm wavelength range. The optically pumped VECSEL is passively modelocked with a semiconductor saturable absorber mirror (SESAM) resulting in 2.7-ps pulses with 89-mW average output power at a center wavelength of 2063 nm and a pulse repetition rate of 1.96 GHz. The standing-wave V-shaped cavity is formed by a 1% output coupler, a VECSEL gain chip as a folding cavity mirror, and a SESAM as the end mirror. An intracavity 1.5-mm silicon plate at Brewster’s angle was used for dispersion compensation and a fixed polarization.
