Abstract :
A simple scheme for generating continuous-wave (CW) terahertz (THz) radiation from a two-colour laser is reported. A Ti-sapphire laser is forced to oscillate on two modes by placing a Fabry-Perot etalon in the laser cavity. THz radiation is generated by photomixing in a biased photoconverter. The THz frequency is determined by the separation of the etalon plates
