Explorations of the Quantum Cascade Laser — with Jerome Faist

December 28, 2021

Jerome Faist, co-inventor of the quantum cascade laser (QCL), reflects on nearly 30 years’ worth of innovations in semiconductor lasing and the history of the QCL. Faist discusses applications in the terahertz and mid-infrared bands, frequency comb spectroscopy, and ultrashort-pulse lasing. Plus, how did the QCL get its name?
