KTP Nonlinear Crystal
KTP Nonlinear Crystal
Potassium titanyl phosphate is widely used in commercial and military lasers, including laboratory and medical systems, range detectors, lidars, optical communications and industrial laser systems. KTP is most commonly used for frequency-doubled Nd:YAG and other Nd-doped lasers, especially in low to medium power lasers. So far, the use of KTP for intracavity and extra cavity frequency doubling of Nd-doped lasers has gradually replaced visible-light dye lasers and tunable sapphire lasers. In many industrial studies, this type of laser is widely used as a green light source.
