Title:
Coherent instabilities in a semiconductor laser with fast gain recovery 
Abstract:
We report the observation of a coherent multimode instability in quantum cascade lasers QCLs, which is driven by the same fundamental mechanism of Rabi oscillations as the elusive Risken-Nummedal-Graham- Haken RNGH instability predicted 40 years ago for ring lasers. The threshold of the observed instability is significantly lower than in the original RNGH instability, which we attribute to saturable-absorption nonlinearity in the laser. Coherent effects, which cannot be reproduced by sta...    »
