The extension of the available spectral range covered by quantum cascade lasers (QCL) would allow one to address new molecular spectroscopy applications, in particular in the long wavelength domain of the mid-infrared. We report in this paper the realization of distributed feedback (DFB) QCLs, made of InAs and AlSb, that demonstrated a continuous wave (CW) and a single mode emission at a wavelength of 17.7 µm, with output powers in the mW range. This is the longest wavelength for DFB QCLs, and for any QCLs or semiconductor lasers in general, operating in a CW at room temperature.

Terahertz (THz) quantum-cascade lasers (QCLs) provide powerful, narrow-band, and frequencytunable radiation, which makes them ideal sources for high-resolution molecular spectroscopy. A first application of a THz QCL has been as local oscillator in a heterodyne spectrometer for astronomy on board a Boeing 747. For laboratory spectroscopy, QCLs close the so-called THz gap and enable new research topics.
