what's potassium titanyl phosphate(KTiOPO4) crystal? where's KTiOPO4(KTP) single crystal? how to buy kalium titanyl phosphate?

DFNano® supplier of nonlinear optical crystal KTiOPO4(KTP); manufacturer of potassium titanyl phosphate(KTiOPO4) crystal in china.

what is KTP (KTiOPO4) ?

KTP (KTiOPO4) is an excellent non-linear crystal. It exhibts high optical quality, broad transparent range, relatively effective SHG coefficient, very high optical damage threshold, wide acceptance angle, small walk-off . 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.
