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 mm and 0.7~0.96 mm 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.
