KTP Crystal

Our KTP crystals feature high purity, low absorption at fundamental and second harmonic generation wavelengths. We supply superior grade and customer-designed KTP crystals for various applications.

Advantages

• Large nonlinear optical (NLO) coefficients
• Wide angular bandwidth and small walk-off angle
• Broad temperature and spectral bandwidths
• 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
