KTP (KTiOPO4) is one of most commonly used nonlinear optical crystals,
which possesses excellent nonlinear and electro-optic properties. It Features
with:
• Large
Nonlinear Optical(NLO) Coefficients
• Wide Phase-matching Acceptance Angle
• Broad Temperature and Spectral Bandwidth
• High Electro-Optic(E-O) Coefficients
• Large Figure of Merit
• Nonhygroscopic, Good Chemical and Mechanical Properties
• Relatively High Damage Threshold for E-O modulator which make it suitable
for various nonlinear frequency conversion and wave guide application.

Applications:
1. SHG of Nd:Laser - KTP is the most commonly used material for frequency
doubling of Nd:YAG and other Nd-doped lasers, particularly when the power
density is at a low or medium level. To date, extra- and intra-cavity
frequency doubled Nd:lasers using KTP have become a preferred pumping
source for visible dye lasers and tunable Ti:Sapphire lasers as well as
their amplifiers. 1mW to 3W TEMoo green laser can be generated by intracavity
SHG in Nd:YVO4 and Nd:YAG laser.
KTP is also being used for intracavity mixing of 0.81µm diode and
1.064µm Nd:YAG laser to generate blue light and intracavity SHG
of Nd:YAG or Nd:YAP lasers at 1.3µm to produce red light.
