Potassium Titanyl Phosphate (KTiOPO4,KTP)
Potassium Titanyl Phosphate (KTiOPO3 or KTP) is widely used in both commercial and military lasers including laboratory and medical systems, range-finders, lidar, optical communication and industrial systems.
SGoptics's 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
