MgO:PPLN Crystals and Waveguides
High Conversion Efficiency: Achieved through the use of a quasi-phase-matching (QPM) phenomenon, utilizing the higher nonlinear coefficient (d33) compared to birefringent phase matching.
Wide Transparent Spectrum: Covers 0.4 to 5 μm.
Enhanced Damage Threshold: 5% MgO doping significantly improves the crystal’s damage threshold.
Convenient Temperature Environment: QPM allows for efficient operation without stringent temperature controls.
Absence of Spatial Walk-Off: Ensures stable and efficient non-linear interactions.
Low Possibility of Photorefractive Issues: Reduces the likelihood of adverse effects during high-power operations.
Applications: Second Harmonic Generation (SHG), Sum Frequency Generation (SFG), Difference Frequency Generation (DFG), Optical Parametric Amplification (OPA), Optical Parametric Oscillation (OPO), Optical Parametric Generation (OPG), etc.
