Abstract

Summary form only given. Generation of cw THz electromagnetic waves by photomixing of two lights from independent two lasers had attracted a great deal of attention. However, each laser in the system should be stabilized separately, and a perfect spatial mode matching was required for efficient THz generation. Optical-alignment procedure is troublesome in practical uses. We report here a novel cw THz wave generation system using a two-longitudinal-mode laser diode (LD) in place of those complex or expensive light sources so far used. The two-longitudinal-mode LD used here radiated two coherent lights with their separation about 0.9THz, simultaneously from a single stripe.
