We demonstrate a high-spectral-purity continuous-wave terahertz source, using a diode pumped Yb3+:CaF2 dual frequency laser. THz radiation is generated by photomixing the two frequencies in a low-temperature grown In. 23Ga. 77As photoconductor, doped with Be, and loading a spiral antenna. The frequency difference between the two optical modes is tuneable by step from d. c. to 2 THz. A maximum laser power of 215 mW CW has been obtained with a beatnote-linewidth narrower than 30 kHz. Measurements show a tuneable THz emission with a maximum output power in the order of few tens nW.
