Abstract
A portable optical pumping source for terahertz radiator is developed in order to provide a military compact solid-state terahertz radiator used in field environment, for the remote sensing for biological early warning detection system, optical electrical countermeasure,photoelectric imaging detection and high-speed communication in the terahertz waveband. Making use of the diode pumped Nd:YAG solid state laser without Thermo Electric Cooler(TEC) temperature control, the laser output energy of 150 mJ, the minimum pulse width of 6 ns, the largest laser frequency 30 Hz , laser beam divergence about 1 mrad are obtained. For the THz wave Parametric Oscillator(TPO)-THz by this pumping source, the 1.63 THz wave with single pulse energy 2.98μJ is achieved, and the THz wave energy conversion efficiency is 1.92×10-5.关键词
