Abstract: The studies of the quantum-cascade laser (QCL) in an external resonator in the Litrov configuration with an output power of up to 1.5 W were carried out. It was shown that the used scheme of the exrenal resonator allows obtaining single-frequency generation with continuous tuning of more than 100 cm$^{-1}$ without antireflection coatings at the QCL facets.

Keywords: integrated optics, quantum cascade laser.
