Non-linear Optical Crystals (NLO Crystals) have extended the laser spectrum from deep UV to far IR by various harmonic generations (like SHG, THG, 4HG, 5HG), sum frequency generations, difference frequency generations, optical parametric oscillators, etc.
Product Description: Potassium Titanium Oxide Phosphate (KTiOPO4 ), or KTP, is an efficient nonlinear optical crystal in the visible to infrared spectral region with relatively low cost. It has large nonlinear coefficient. The effective nonlinear optical coefficient of KTP deff at 1064nm is more than 1.5 times that of BBO. It's damage threshold is near 1 GW/cm2 for 1 Hz 10 ns pulses at 1064nm.
Application: KTP crystal is a kind of popular nonlinear optical crystal with excellent nonlinear optical properties. As a frequency conversion optical material, KTP crystal had been widely used in scientific research and technique and many other fields, especial best for small and medium-sized power frequency doubling. Frequency doubler and photoparametric amplifier produced by KTP crystal had been had been applied in solid-state tunable laser light source. he properties of KTP make it superior as an electro-optic modulator as well as an optical waveguide device, including phase modulators, amplitude modulators and directional couplers.
Advantage: KTP crystal also have large temperature and angle tolerance.
KTP crystals have very important nonlinear characteristics as follows,
Large nonlinear optical coefficient(about 15 times large than that of KDP)
Wide receiving angle and small walk-off angle
Wide transmittance
High photoelectric conversion efficiency and low dielectric constant
Good physics, chemistry and mechanical property
High heat transfer coefficient (two times high than BBN crystal)
Low dismatch
Cost-effective compared with BBO and LBO
