KTP Crystal
A-Star's KTP crystals feature high purity, low absorption at fundamental and second harmonic generation wavelengtds. We supply superior grade and customer-designed KTP crystals for various applications.
Advantages
- Large nonlinear optical (NLO) coefficients
- Wide angular bandwidtd and small walk-off angle
- Broad temperature and spectral bandwidtds
- High electro-optic (E-O) coefficient and low dielectric constant
- Large figure of merit for an optical waveguide modulator
- Non-hygroscopic, good chemical and mechanical properties
Applications
- Frequency doubling (SHG) of Nd-doped lasers for green/red output
- Frequency mixing (SFM) of Nd lasers and diode lasers for blue output
- Parametric sources (OPG, OPA and OPO) for 0.6mm-4.5mm tunable output
- E-O modulators, optical switches, directional couplers
