Author Affiliations +
The MIXSEL combines the gain of a VECSEL with the saturable absorber of a SESAM in one semiconductor structure to achieve fundamental modelocking in a simple straight cavity. We present a high-power MIXSEL with sub-10-ps pulse durations that can be scaled easily in repetition rate from a few GHz to <100 GHz. At 5.1 GHz repetition rate an average output power of 1.05 W in 2.4-ps-pulses was achieved. By scaling the repetition rate to 10 GHz (3.9-ps-pulses at 1.29 W), then to 20.7 GHz (2.35-ps-pulses at 607 mW) and most recently to even more than 100 GHz makes this high-power MIXSEL an attractive source suitable for applications such as optical clocking or optical sampling.
