We report a repetition frequency tunable, passively mode-locked vertical-external-cavity surface-emitting semiconductor laser (VECSEL) with continuous repetition frequency tuning between 2.78 and 7.87 GHz using mechanical tuning of the laser cavity length. The laser emits near-transform-limited, sub-500-fs pulses over almost an octave tuning range between(More)
The pulse evolution from onset to steady state in a mode-locked vertical-external-cavity surface-emitting laser producing femtosecond and picosecond pulses was studied. A 40-times reduction in pulse shortening rate from picosecond to femtosecond regime was observed.
