磷酸氧钛钾（KTiOPO4，简称KTP）晶体是目前非线性晶体中综合性能*好的晶体之一，其较大的非线性系数，较高的*光损光损伤阈值、稳定化学特性，不潮解，机械性能良好，晶体表面易于抛光，失配度小，适用于制作倍频器，其对1064nm的倍频效率可达约80％。该晶体可用于制作倍频、混频、电光调制、光学参量振荡和光学波导等元器件，*高的倍频转化效率和相对较低廉的价格使其在该类晶体的应用领域中一直*不衰，尤其是对于近红外激光倍频，KTP是*好的晶体材料。
Pot*ium Titany Phosphate(KTiOPO4or KTP) is widely used in both commercial and military lasers including laboratory and medical systems, range-finders, lidar, optical communication and industrial systems. It has a lot of exceptional properties as followings:
l Large nonlinear optical coefficient
l Wide angular bandwidth and *all walk-off angle
l Broad temperature and spectral bandwidth
l High electro-optic coefficient and low dielectric constant
l Large figure of merit
l Nonhydroscopic, chemically and mechanically stable
KTP is the most commonly used material for frequency doubling of Nd:YAG and other Nd-*d lasers, particularly for the low or medium level power density. Applied to diode-pumped Nd:YVO4lasers, KTP has provided the basis for the construction of compact green solid state laser systems in industry applications
