A 1.55 μm VECSEL with a hybrid metal-GaAs/AlAs metamorphic mirror optimized for high power room temperature operation has been assembled with a fast InGaAsN/GaAsN saturable absorber mirror (SESAM) to generate mode-locked pulses at a frequency of 2 GHz. Nearly Fourier transform-limited pulses are obtained at 25 °C avoiding the need for water cooling, with a pulsewidth <; 2 ps. The RF linewidth of...
A 1.55μm VECSEL with a metal-GaAs/AlAs hybrid metamorphic mirror optimized for high power room temperature operation has been assembled with a fast saturable absorber mirror (SESAM) in a four-mirror cavity to generate mode-locked pulses at a frequency of 2 GHz. Stable pulses are obtained at room temperature avoiding the need for water cooling, with a pulsewidth <; 2 ps and an average optical power...
