Abstract
We present timing jitter measurements of a free-running SESAM modelocked VECSEL generating 8-ps pulses with 1.88-GHz repetition rate and 80-mW average output power. We observed very good performance comparable with iondoped solid-state-lasers which typically show excellent stability. We measured the two-sided noise power spectral density at the 10th harmonic of the laser output with the von der Linde method. The rms timing jitter integrated over an offset frequency range from 100 Hz to 100 kHz gives a free-running timing jitter of ≈400 fs which is an upper limit because the measurement was already system noise limited above 10 kHz.
