Product Description

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.

Advantages

•   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
