Coherent instabilities in a semiconductor laser with fast gain recovery
(American Physical Society, 2007)
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) ...
Multimode regimes in quantum cascade lasers: From coherent instabilities to spatial hole burning RID B-8648-2009
(American Physical Society, 2008)
A theoretical and experimental study of multimode operation regimes in quantum cascade lasers (QCLs) is presented. It is shown that the fast gain recovery of QCLs promotes two multimode regimes: One is spatial hole burning ...
