The tunable, continuous-wave terahertz (THz) radiation generated by mixing of two near-infrared laser lines in an antenna-coupled photomixer is compared with the monochromatic beam of backward-wave oscillators. The electromagnetic radiation of the different THz sources is characterized with respect to intensity, linewidth, degree of linear polarization, angular characteristic, beam quality, and M 2 value. The results are discussed with respect to applications in THz spectroscopy and imaging.
