Product Description Potassium Titanyl Phosphate (KTiOPO4,KTP) KTP (KTiOPO4) is an excellent non-linear crystal. It exhibts high optical quality, broad transparent range, relatively effective SHG coefficient ( about 3 times higher than that of KDP), very high optical damage threshold, wide acceptance angle, small walk-off , and type 1and type 2 non-critial phase-matching (NCPM) in a wide wavelength range. KTP is the most commonly used material for frequency doubling of Nd:YAG laser and other Nd-doped lasers, particularly at the low or medium power density. The properties of KTP make it superior as an electro-optic modulator as well as an optical waveguide device, including phase modulators, amplitude modulators and directional couplers.
