KTP crystal 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 also has high electro-optic(E-O) coefficient and low dielectric constant, and large figure of merit, these features make it also widely used in electro-optic application.

Advantages of KTP Crystal:

Large Nonlinear Optical (NLO) Coefficients

Wide Angular Bandwidth and Small Walk-off Angle

Broad Temperature and Spectral Bandwidth

High Electro-Optic (E-O) Coefficient and Low Dielectric Constant

Large Figure of Merit for an Optical Waveguide Modulator

Nonhygroscopic, Good Chemical and Mechanical Properties
