Single-mode instability in standing-wave lasers: The quantum cascade laser as a self-pumped parametric oscillator
We report the observation of a clear single-mode instability threshold in continuous-wave Fabry-Perot quantum cascade lasers (QCLs). The instability is characterized by the appearance of sidebands separated by tens of free spectral ranges (FSR) from the first lasing mode, at a pump current not much...
