Potassium Titanyl Phosphate (KTiOPO3 or KTP) is an excellent optical crystals suitable for use in many optical systems. It has high nonlinear coefficient and stable physical property. Its most popular application is as a frequency doubler of 1064nm to generate 532nm laser. KTP's properties also make it superior for electro-optic modulation (EO components), optical parametric generation (OPO or OPA components). KTP crystals are widely used in commercial and military lasers including laboratory and medical systems, range-finders, lidar, and industrial systems.
