Potassium Titanyl Phosphate (KTiOPO4 or KTP) is an excellent nonlinear optical content well suited for use in lots of optical techniques. It has large nonlinear coefficient and secure Bodily property.
Comparison involving shared and coupled resonators for passively Q-switched Nd:GdVO4 intracavity optical parametric oscillators
They can be manufactured at an optimally very low temperature that reduces the probability of defects, oxygen vacancies, crystal strains, or diminished steel centers.
Dependant on the gray monitoring resistance (GTR) KTP crystals, the performance of a substantial economical and compact intracavity frequency doubling 532 nm laser was investigated. The grey tracking check…
The incidence of grey-keep track of can be measured by an increase of bulk absorption by a powerful CW 532nm eco-friendly laser in quite a few minutes. This measurement is usually performed with Photo-thermal Typical-path interferometer.

CASTECH's GRT-KTP, as a superb NLO crystal, has decreased absorption and better harm threshold than the traditional KTP, which we could conclude it possesses a higher gray monitor resistance.
Its most widely used software is like a frequency doubler using the 1064nm output of a Nd:YAG laser also to crank out 532nm laser. KTP’s Houses also ensure it is outstanding for electro-optic modulation, optical parametric generation.
These crystals have a decrease Original IR absorption and are considerably less afflicted by eco-friendly gentle than frequent KTP, Therefore keep away from the issues of harmonic power instabilities, effectiveness drops, crystal blackening, and beam distortion.
Take note: Writer names might be searched from the keywords and phrases discipline, also, but that could uncover papers wherever the individual is outlined, rather than papers they authored.
The crystals are generally accustomed to double the frequency of Nd:YAG and Nd:YVO�?lasers, creating noticeable green laser output (532 nm) from the elemental 1064 nm wavelength.

Immediately after air drying and subsequent cleansing by using a cotton cloth soaked in alcohol, the film area confirmed no indications of peeling or scratches.
We report an intracavity optical parametric oscillator at 1.57 μm based on non-critically more info nonlinear crystal KTP driven by an stop-pumped acousto-optically Q-switched Nd:LuVO4 crystal. The output…
The prevalence of grey-observe is often measured by a boost of bulk absorption by a powerful CW 532nm green laser inside several minutes. This measurement could be carried out with Picture-thermal Widespread-route interferometer.
