Potassium Titanyl Phosphate (KTiOPO4 or KTP) is a wonderful nonlinear optical material suited to use in lots of optical units. It's got higher nonlinear coefficient and stable physical home.
Comparison between shared and coupled resonators for passively Q-switched Nd:GdVO4 intracavity optical parametric oscillators
They can be made at an optimally low temperature that minimizes the probability of defects, oxygen vacancies, crystal strains, or diminished metallic facilities.
KTP is an excellent nonlinear crystal, but its grey monitoring phenomena boundaries its use in substantial repetition price and large electricity laser devices. CASTECH's GTR-KTP crystal has higher gray tracking resistance compared to the common flux grown KTP crystal.

Its most widely used software is to be a frequency doubler employing the 1064nm output of the Nd:YAG laser and also to make 532nm laser. KTP’s Houses also make it remarkable for electro-optic modulation, optical parametric era.
These types of crystals have a decreased Preliminary IR absorption and are much less affected by green gentle than standard KTP, Hence stay clear of the issues of harmonic electrical power instabilities, efficiency drops, crystal blackening, and beam distortion.
Notice: Author names might be searched inside the keywords discipline, also, but which will locate papers where by the person is stated, rather than papers they authored.
The crystals are generally used to double the frequency of Nd:YAG and Nd:YVO�?lasers, producing visible green laser output (532 nm) from the elemental 1064 nm wavelength.

CASTECH's GRT-KTP, as a great NLO crystal, has lower absorption and better injury threshold than the traditional KTP, which we will conclude it possesses a higher grey keep track of resistance. Quantity of sights:
We report an intracavity optical parametric oscillator at GTR-KTP Crystal 1.57 μm according to non-critically nonlinear crystal KTP pushed by an close-pumped acousto-optically Q-switched Nd:LuVO4 crystal. The output…
The occurrence of grey-monitor can be calculated by an increase of bulk absorption by a solid CW 532nm inexperienced laser inside several minutes. This measurement may be done with Photo-thermal Typical-route interferometer.
