Potassium Titanyl Phosphate-KTP

Potassium titanyl phosphate (KTP or KTiOPO4) is a nonlinear optical material
suitable for many optical systems. Its most popular application is as a frequency
doubler utilizing the 1.06 µm output of a ND:YAG Laser. The conversation efficiency to 0.53 µm is up to
70% at 300 MW/cm2
. KTP's properties also make it superior as an electro optic modulator, optical
parametric generation and optical waveguiding.
KTP's unique combination of properties, high nonlinear coefficients, high damage threshold, and the fact
that it is nonhygroscopic as well, suit it to those laser system applications requiring high power, high
efficiency, and/or durability. It can be used in both commercial and military laser including medical and
laboratory systems, range finders, designators and systems for use in the semiconductors industry.
