Periodically Poled Lithium Niobate (PPLN) is a highly efﬁcient crystal for nonlinear wavelength conversion process- es, which has awide light transmission range and covers the NIRand MIR spectral regions, PPLN is usedfor SHG,SF- G,OPO,and other nonlinear processes from Visible to MIR. In order to meet the requirements of modern optics for diverse laser wavelengths. the output of any wavelength in the transmittance range can be realized through the design of periodic structure. PPLN crystals have been widely used in laser display, environmental detection, mid-in- frared spectroscopy, all-optical wavelength conversion, optical sensing and other ﬁelds. The optical damage thresh- old and photorefractive threshold of the crystal can be greatly improved by MgO doping, while maintaining high nonlinear coefﬁcient. Compared with PPLN of the same composition, MgO:PPLN crystal can work more stably at lower temperature and visible light range.
