Nonlinear Crystal, KTP

Overview:

KTP (KTiOPO4) is an excellent nonlinear optical crystal in many optical systems like laboratory system, medical system, industrial system, etc. It 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. KTP’s properties also make it superior for electro-optic modulation, optical parametric generation.
