Laser Crystals and Components
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 Waveguide 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 off-the-shelf and custom MgO:PPLN waveguides, and standard stocked waveguides designed for SHG, OPO, SFG and DFG are listed for your choice. Shalom EO also provides the 532nm and 561nm compact green laser OEM modules made of 808nm laser diode, Nd:YVO4 crystals and MgO:PPLN crystals integration, and laser modules of 473nm, 532nm,545nm, 561nm and 671nm using MgO:PPLN as the SHG.
