KTP Crystal

  • Introduction

KTP crystal design

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
