Paper Abstract

We present a VECSEL based on a gain sample design which utilizes only a single-layer dielectric Al2O3 coating for dispersion management. The gain structure generated pulse durations down to 193 fs in combination with a surface-recombination SESAM, with an average power of 400 mW at 1.6 GHz setting a new peak power record for sub-200 fs mode-locked VECSELs. The pulses obtained were, however, 2x transform-limited and a further FROG measurement of a similar laser is presented revealing a linear chirp and cubic spectral phase.
