KTP is a superb nonlinear crystal, but its grey tracking phenomena boundaries its use in high repetition fee and superior electricity laser systems. CASTECH's GTR-KTP crystal has bigger grey tracking resistance when compared to the normal flux grown KTP crystal.
Through Photo-thermal Frequent-path Interferometer, the incidence of gray monitoring is often measured by a rise of bulk absorption by way of a potent CW 532 nm green laser inside of several minutes.

Really effective intracavity frequency doubling 532-nm laser based upon The grey tracking resistance KTP crystal
Its most favored application is as a frequency doubler employing the 1064nm output of the Nd:YAG laser also to make 532nm laser. KTP’s Houses also allow it to be remarkable for electro-optic modulation, optical parametric generation.
These kinds of crystals Possess a reduce Original IR absorption and so are significantly less afflicted by inexperienced mild than regular KTP, Consequently stay clear of the issues of harmonic electrical power instabilities, efficiency drops, crystal blackening, and beam distortion.
Additionally, the closed autoclave advancement technique permits zero to nominal chemical impurities as well as constant progress charge lends an outstanding homogeneity or uniform generate through the entire bulk crystal.
The crystals are generally used to double the frequency of Nd:YAG and Nd:YVO�?lasers, generating GTR-KTP Crystal seen green laser output (532 nm) from the elemental 1064 nm wavelength.
