KTP Nonlinear Crystals
KTP crystal (KTiOPO4) is mostly used as nonlinear crystals for frequency doubling of solid-state Nd:YAG crystal or Nd:YVO4 crystal laser, as it has large nonlinear optical coefficients, wide angular bandwidth and small walk-off angle, broad temperature and spectral bandwidth
KTP Crystal Advantages:
1. Large Nonlinear Optical (NLO) Coefficients
2. Wide Angular Bandwidth and Small Walk-off Angle
3. Broad Temperature and Spectral Bandwidth
4. High Electro-Optic (E-O) Coefficient and Low Dielectric Constant
5. Large Figure of Merit for an Optical Waveguide Modulator
6. Nonhygroscopic, Good Chemical and Mechanical Properties
KTP Crystal Applications:
1. Frequency Doubling (SHG) of Nd-doped Lasers for Green/Red Output.
2. Frequency Mixing (SFM) of Nd Laser and Diode Laser for Blue Output.
3. Parametric Sources (OPG, OPA and OPO) for 0.6mm-4.5mm Tunable Output.
4. E-O Modulators, Optical Switches, Directional Couplers.
5. Optical Waveguides for Integrated NLO and E-O Devices.
