Abstract :
Summary form only given. We generated a sub-THz coherent radiation by using a two-longitudinal mode laser diode (LD). The laser beam was mixed on a low-temperature grown (LTG) GaAs photoconductive dipole antenna for generation of a radiation with a frequency corresponding to the mode separation of the LD. Due to the common-mode rejection effect of the identical laser cavity, the spectral linewidth of the generated radiation is approximately more than two times narrower compared with that of each mode of the LD.
