摘要：
The collinearly phase-matching condition of terahertz-wave generation via difference frequency mixed in GaAs and InP is theoretically studied. In collinear phase-matching, the optimum phase-matching wave bands of these two crystals are calculated. The optimum phase-matching wave bands in GaAs and InP are 0.95-1.38 μm and 0.7-0.96 μm respectively. The influence of the wavelength choice of the pump wave on the coherent length in THz-wave tuning is also discussed. The influence of the temperature alteration on the phase-matching and the temperature tuning properties in GaAs crystal are calculated and analyzed. It can serve for the following experiments as a theoretical evidence and a reference as well. © 2008 Tianjin University of Technology and Springer-Verlag GmbH.
