PPLN (Periodically Poled Lithium Niobate)
PPLN is a highly efficient nonlinear optical crystal based on the core principle of Quasi-Phase Matching (QPM). By periodically reversing the polarization direction within the crystal, it effectively compensates for phase mismatches, significantly boosting the efficiency of laser wavelength conversion.
Main Categories
- Bulk PPLN: Ideal for standard free-space optical setups, widely used in high-power laser systems.
- Waveguide PPLN: Confines light within micro-scale channels, offering ultra-high conversion efficiency and easy integration with optical fibers.
- Doped PPLN: Enhanced with Magnesium Oxide (MgO) to significantly improve resistance to optical damage, making it perfect for high-power applications and stable room-temperature operation.
