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.
