| Abstract: | 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 to200 °C. The calculated continuous-tunable Mid-IR wavelength range of the OPO system is from 1.355 μm to 1.735μm and 2.75 μm to 4.948 μm. Meanwhile, the relationship of work temperature, grating period and output wavelength has been analyzed. |
