Description

Potassium Titanyl Phosphate (KTiOPO₄,KTP)

Potassium Titanyl Phosphate (KTiOPO₃ or KTP) is widely used in both commercial lasers including laboratory and medical systems, range-finders, lidar, optical communication and industrial systems.
KTP is featured by
•Large nonlinear optical coefficient
•Wide angular bandwidth and small walk-off angle
•Broad temperature and spectral bandwidth
•High electro-optic coefficient and low dielectric constant
•Large figure of merit
•Nonhydroscopic, chemically and mechanically stable
