    Abstract

    We present a 10 GHz passively mode-locked vertical external-cavity surface-emitting semiconductor laser (VECSEL) with 1.4 W average output power in 6.1 ps pulses. The output features a very good pulse quality with a time-bandwidth product of 0.42 in a nearly diffraction-limited beam. This demonstrates that passively mode-locked VECSELs are suitable for generating high powers in high-repetition-rate pulse trains. (C) 2005 American Institute of Physics.
