Abstract

Optically pumped SESAM modelocked semiconductor disk lasers (SDLs) or vertical-external-cavity surface-emitting lasers (VECSELs) are of great interest for applications that require compact and high-power sources with ultrashort pulses and excellent beam quality. The modelocked integrated external-cavity surface emitting laser (MIXSEL) combines the gain of VECSELs with the saturable absorber of a semiconductor saturable absorber mirror (SESAM) in a single semiconductor device. Hence, self-starting and stable passive modelocking is obtained in a simple straight cavity formed by the semiconductor chip and a curved output coupler. Record high average output power of 6.4 W from a picosecond MIXSEL confirmed the high potential of this technology.
