Abstract: It was January 1994, when the first quantum cascade laser (QCL) displayed laser action in Bell Laboratories. During these 30 years the QCL evolved incessantly, from a lab curiosity to the main on-chip source of coherent radiation in the Mid-IR and THz ranges. The journey has seen an impressive development of the QCL in several fields of laser physics and its applications, with a steady growth of research groups and companies worldwide. The 30-years development of quantum cascade lasers has established them as a go-to source of coherent radiation in the Mid-IR and THz ranges. In this comment, the authors guide the reader through the landmark achievements of this technology, from a lab curiosity to a mature technology adopted by research groups and companies.
