Abstract

The generation of continuous wave (CW) tunable far infrared (FIR) radiation by mixing a quantum cascade laser (QCL) and a carbon dioxide laser in a W-Ni metal insulator metal diode was demonstrated. It was also demonstrated that the radiation could be used for spectroscopy by recording the J=8→9 rotational line of H ⁷⁹Br. The FIR power generated by using two gas lasers was compared to the set up with the QCL. First-derivative line shapes were obtained by adding a sinusoidal signal at 1.1 kHz to the current ramp.
