Timing Jitter Characterization of a Free-Running SESAM Mode-locked VECSEL

IEEE Photonics Journal, 2011
We present timing jitter measurements of an InGaAs quantum well vertical external cavity surface emitting laser (VECSEL) passively mode locked with a quantum dot semiconductor saturable absorber mirror (SESAM) at 2-GHz repetition rate. It generates 53-mW
