KTiOPO4 (KTP-Nonlinear Crystal) has the following characteristics:

A high nonlinear coefficient (about 15 times that of KDP)
High thermal conductivity (twice that of BDN crystal)
A wide range of allowable temperature matching and allowable angle matching
A high threshold of resistance to gray traces and light damage
No moisture absorption and deliquescence
No decomposition below 900 °C
Good mechanical properties
Easy polishing of the crystal surface, and small mismatch

Its frequency doubling efficiency at 1064 nm can reach about 80%. The crystal can be used to make components for frequency doubling, frequency mixing, electro-optical modulation, optical parametric oscillation and optical waveguide.

Features of KTP Crystals:
High temperature resistance
High thermal conductivity
The mismatch is small
The impedance ratio is large
Broad band of light transmission
Low temperature sensitivity
Good mechanical properties
Large nonlinear optical coefficient
Chemical and mechanical properties are stable
High photoelectric coefficient and low dielectric constant
