Potassium titanyl phosphate ( KTP) is an ionic compound consisting of potassium oxide, titanium oxide and phosphate, their crystals have non-linear optical properties, which makes it in addition to a fairly wide transparency range of 350 nm to 4400 nm for the optical system of interest. It was first synthesized in 1890 by L. Ouvard.

Applications

KTP crystals may be used for electro-optical and non-linear optical applications. A common application is the frequency-doubling of laser light by placing a KTP crystal in the laser resonator. The best known example is the green DPSS laser. YVO4 or Nd: YAG laser produces light at a wavelength of 1064 nm, which is then converted by frequency doubling into visible green radiation with a wavelength of 532 nm, here, first by means of a Nd. These radiation sources are also known as " KTP laser ". In quantum optics, KTP plays a role for the generation of correlated photon pairs by parametric fluorescence.
