Frequently Asked Questions

KTP crystals have 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, efficient frequency conversion, large nonlinear optical coefficients, high thermal conductivity, and low cost compared with BBO and LBO.

KTP crystals have a flank size (W*H) of 1×1~15×15, length (L) of 0.05~20mm, angle tolerance of Δθ<±0.2°;Δφ<±0.2°, size tolerance of (W±0.1mm)x(H±0.1mm)x(L+0.2mm/-0.1mm), flatness of <λ/8@633nm, surface quality of 60/40scratchanddig, parallelism of <30", perpendicularity of <10', wavefront distortion of <λ/8@633nm, clear aperture of >90%, and coating upon customer's request.

KTP crystals are used for frequency mixing (SFM) of Nd Laser and Diode Laser for Blue Output, frequency doubling (SHG) of Nd-doped Lasers for Green/Red Output, parametric sources (OPG, OPA and OPO) for 0.6um-4.5um Tunable Output, E-O modulators, optical switches, directional couplers, and optical waveguides for integrated NLO and E-O devices.

KTP stands for Potassium Titanium Oxide Phosphate. It is an efficient nonlinear optical crystal that operates in the visible to infrared spectral region with relatively low cost.
