Mode-locked ultrashort pulses from an 8 m wavelength semiconductor laser

Johannes Hillbrand, Nikola Opacak, Marco Piccardo +4

Quantum cascade lasers (QCL) have revolutionized the generation of mid-infrared light. Yet, the ultrafast carrier transport in mid-infrared QCLs has so far constituted a seemingly…
