MgO:Periodically Poled Lithium Niobate  (PPLN)  Waveguide Laser Modules consist of MgO:PPLN waveguide integrated with the pumping laser diode (LD), Nd:YVO4 or Nd:YAG laser crystals and other accompanied optics. The pumping LD functions as the pumping source for the laser crystals, after the laser crystal generates 1064nm (from Nd:YAG) or 1122nm (from Nd:YVO4) laser light, the MgO doped PPLN waveguide is utilized for the nonlinear optical process, transforms the received laser light into other desired wavelengths. 

Shanghai North Optics offers various off-the-shelf and custom laser modules installed with MgO:PPLN waveguides, the available standard output wavelengths include: 473nm, 532nm,545nm, 561nm, and 671nm, whilst other custom output wavelengths are also accessible upon requests. North Optics's MgO:PPLN waveguide laser modules feature a compact dimensional design and are a small-size kind of laser module, permitting convenient integration into your whole laser system. Our MgO:PPLN waveguide laser modules also boast high output power and superb conversion efficiencies, our sales group is capable of delivering waveguide laser modules within a short time scale, presenting users access to a wide range of wavelengths.
