KTP is a wonderful nonlinear crystal, but its gray tracking phenomena restrictions its use in large repetition level and large power laser techniques. CASTECH's GTR-KTP crystal has larger grey tracking resistance in comparison to the regular flux grown KTP crystal.
As a result of Photo-thermal Frequent-path Interferometer, the incidence of gray tracking is often measured by a boost of bulk absorption through a powerful CW 532 nm inexperienced laser in just quite a few minutes.
By way of Photograph-thermal Common-path Interferometer, the prevalence of grey tracking is usually calculated by a boost of bulk absorption through a strong CW 532 nm green laser within quite a few minutes.
CRYSTECH has in excess of 20 years of KTP advancement and processing practical experience. The crystal expansion course of action is optimized to deliver superior-excellent and productive crystals, and also the coating system is specifically intended to offer a comparatively greater destruction threshold.

The event of gray-track can be calculated by a boost of bulk absorption by a robust CW 532nm eco-friendly laser inside of a number of minutes. This measurement could be carried out with Photo-thermal Popular-route interferometer.

Potential of most cancers screening with serum surface-Improved Raman spectroscopy along with a aid vector machine
GTR-KTP crystals, produced with revolutionary manufacturing procedures, exhibit significantly better resistance to gray monitoring and reduced absorption within the UV and visual regions, building them appropriate for a variety of programs such as frequency doubling, parametric oscillation, and laser amplification.

Adhesion Examination Compliant with MIL-C-675C military criteria, an adhesion check associated applying a tape that fulfills LT-ninety specifications on to the lens film layer. The tape was affixed thoroughly and afterwards taken off vertically. This method was performed 3 times, causing no blistering or peeling.
