KTP Crystals and Components

KTP (KTiOPO4) is a nonlinear optical crystal, which possesses excellent nonlinear and electro-optic properties.It has large nonlinear optical coefficients and wide angular bandwidth and small walk-off angle,etc.which make it suitable for various nonlinear frequency conversion and wave guide online_ordering.

KTP crystals are also optimised for SHG intracavity configuration in low peak power CW lasers. Due to the large number of passes through the crystal, low insertion losses and high homogeneity are essential for conversion efficiency. The special highest quality material selected by SHG efficiency mapping of each crystal, fine surface polishing and dual band AR coatings with very low losses allow ULTI Crystal to produce KTP crystals suitable for intracavity SHG application.


Fig. 1 represents Type 2 SHG tuning curve of KTP in x-y plane. In x-y plane the slope ∂(Δk)/∂θ is small. This corresponds to quasi-angular noncritical phase-matching, which ensures the double advantage of a large acceptance angle and a small walk off. Otherwise in x-z plane the slope
∂(Δk)/∂λ is almost zero for wavelengths in the range 1.5–2.5 μm and this corresponds to quasi-wavelength noncritical phasematching, which ensures a large spectral acceptance (see Fig. 2). Wavelength noncritical phase-matching is highly desirable for frequency conversion of short pulses. As a lasing material for OPG, OPA or OPO, KTP can most usefully be pumped by Nd lasers and their second harmonic or any other source with intermediate wavelength, such as a dye laser (near 600 nm). Fig. 3 and Fig. 4 show the phasematching angles for OPO/OPA pumped at 532 nm in x-y and x-z plane respectively.
