In this paper, we calculate the output wavelengths of OPO based on quasi-phase matching technology and MgO:PPLN crystal. In the OPO system, the pump source was a 1.064μm laser;the used crystal was MgO:PPLN with different grating periods of 26-31μm (the interval is 0.5μm);the operating temperature changed from 40 ° C to 200 ° C. The calculated continuous-tunable Mid-IR wavelength range of the OPO system is from 1.355μm to 1.735μm and 2.75 μm to 4.948 μm. Meanwhile, the relationship of work temperature, grating period and output wave-length has been analyzed.
