Periodically poled lithium niobate (PPLN) waveguides are a type of high efficiency non-linear optical crystals, which cover a extremely wide wavelength conversion spectral range of 0.4μm to 5.0μm. The 5% MgO doping in LiNbO3 would increase the optical resistance of the crystals and significantly improve its damage threshold. MgO:PPLN could be used as Second Harmonic Generation (SHG), Optical Parametric Oscillator (OPO), Optical Parametric Amplifier (OPA), Sum Frequency Generation (SFG) and Difference Frequency Generation (DFG). By choosing proper period, width and length, one can get required specific frequency conversion.

Hangzhou Shalom EO offers a series of PPLN waveguide chips for SHG of 976nm, 1029nm,1064nm, 1545nm, 1550nm, 1560nm and 2100nm, the PPLN crystals for SFG, DFG and OPO applications are also available.
