KTP Crystals 8x8x20mm for OPO@1064nm to 1570nm, Code: 20203-019
Potassium Titanyl Phosphate (KTiOPO3 or KTP) is an excellent optical crystal suitable for use in many optical systems. It has a 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.
Size up to 20x20x40mm^3 and length up to 60mm
