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 M2 value. The results are discussed with respect to applications in THz spectroscopy and imaging.
