Regular Self-Pulsations in External Cavity Mid-IR Quantum Cascade Lasers

Nikola N. Vukovic, Jelena V. Radovanovic, Vitomir B. Milanovic +4

We show theoretically and experimentally that a quantum cascade laser (QCL) in an external Fabry-Perot cavity (EC) can produce regular self-pulsations (SP) of the output intensity…
