KTP is a positive biaxial crystal, with the principal axes X, Y, and Z (nz>ny>nx) parallel to the crystallographic axes a, b, and c, respectively.

High damage threshold
Without gary-track in high power cw intracavity application
Lower absorption in 532nm
Higher resistivity

Parametric sources (OPG, OPA and OPO) for 600nm-4500nm tunable outputs.
E-O modulators, optical switches, directional couplers.
Optical waveguides for integrated NLO and E-O devices.
