Laser Crystals and Components
Periodically poled lithium niobate (PPLN) is a type of high efficiency non-linear optical crystals, which covers 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 the off-the-shelf and custom MgO:PPLN crystals, standard stocked crystals designed for SHG, OPO, SFG and DFG are listed for your choice. Shalom EO also offers the 532nm and 561nm compact green laser OEM modules made of 808nm laser diode, Nd:YVO4 crystals and MgO:PPLN crystals integration, and the laser modules of 473nm, 532nm,545nm, 561nm and 671nm using MgO:PPLN as the SHG.
