Abstract

We report the research results on Solid-State Laser System for Terahertz Radiation Generation. Terahertz radiation generation is based on a double longitudinal mode laser with a single linear cavity and laser amplifiers. The laser is LD pumped CW Nd:YVO4 laser with a single linear cavity. The double longitudinal mode laser beam makes it very convenient to control their propagation for Terahertz radiation generation. The relative intensities of the modes and the frequency difference between the modes can be adjusted for high efficiency generating THz radiation with required frequency. The CW laser beam was first amplified by a LD end-pumped Nd:YVO4 amplifier, then it was changed into pulsed beam by an LN electro-optical modulator. The pulsed laser beam was amplified by other four Nd:YVO4 amplifiers pumped by three 6W LDs and a 35W optical fiber coupled LDA, respectively, and became strong enough and was projected into an organic nonlinear optical crystal DAST to generate THz radiation with narrow linewidth and stable frequency. By this method a new kind of THz wave source can be developed. It is smaller in size, high efficient and no any adjustment is needed in applications. The paper reports the experimental setup and results in details.
