Product Description

Potassium Titany Phosphate (KTiOPO4, KTP)Potassium Titany Phosphate (KTiOPO4, KTP)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
