We demonstrate the generation of cw tunable far-infrared radiation by mixing a quantum cascade laser and a CO>2 laser in a W–Ni metal–insulator–metal diode. The first known spectroscopic application to the recording of an H79Br transition near 4.47 THz is reported.

Abstract
We demonstrate the generation of cw tunable far-infrared radiation by mixing a quantum cascade laser and a CO>2 laser in a W–Ni metal–insulator–metal diode. The first known spectroscopic application to the recording of an H79Br transition near 4.47 THz is reported.
