Potassium titanyl phosphate, KTP, combines nonlinear conversion with useful electro-optic properties. Common applications include Nd:YAG frequency doubling and near-infrared parametric generation; phase matching and thermal conditions govern the configuration.
Properties, applications and specifications
KTP (Potassium Titanyl Phosphate, KTiOPO4) is a nonlinear optical material generally used for doubling of solid-state lasers, such as Nd:YAG. The crystal has a relatively high optical damage threshold, a large optical nonlinearity of second-harmonic generation (SHG) and excellent thermal stability. Its SHG coefficient is approximately three times higher than KDP, and it is often used as an optical parametric oscillator (OPO) for near IR generation up to 3 µm.
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 Non-hydroscopic, chemically and mechanically stable High thermal conductivity Moisture free Minimum mismatch gradient Low cost compare with BBO and LBO
