GTR-KTP crystals are greatly used in apps that desire significant-performance nonlinear optical supplies with improved longevity and resistance to grey tracking. Some notable purposes involve:
Enhanced bulk absorption Qualities, lowering IR absorption and strengthening Total optical functionality.
They are really produced at an optimally very low temperature that reduces the probability of defects, oxygen vacancies, crystal strains, or lowered steel facilities.
A compact effective eye-Secure intracavity optical parametric oscillator pumped by a passively Q-switched Nd:YAG laser inside of a shared cavity configuration with efficient conversion effectiveness as significant as fifty one% is introduced.
The event of gray-keep track of is often measured by an increase of bulk absorption by a solid CW 532nm inexperienced laser inside of many minutes. This measurement could be performed with Picture-thermal Frequent-path interferometer.

CRYSTECH has a lot more than 20 years of KTP growth and processing experience. The crystal advancement procedure has become optimized to supply large-top quality and effective crystals, and also the coating process is specifically meant to supply a relatively higher hurt threshold.
This phenomenon is correlated with “gray tracking impact�? The following graphs display the absorption level changes as time passes at 1064 nm for CASTECH's GTR-KTP and the standard KTP independently
Flux developed KTP crystals offer a greater price tag edge. It is additionally conveniently fabricated in larger Proportions.
Note: Writer names might be searched in the search phrases subject, also, but which will discover papers in which the person is mentioned, instead of get more info papers they authored.
The crystals are generally accustomed to double the frequency of Nd:YAG and Nd:YVO�?lasers, producing obvious eco-friendly laser output (532 nm) from the elemental 1064 nm wavelength.

Right after air drying and subsequent cleaning having a cotton cloth soaked in Alcoholic beverages, the movie floor showed no signs of peeling or scratches.
We report an intracavity optical parametric oscillator at one.fifty seven μm based on non-critically nonlinear crystal KTP driven by an conclude-pumped acousto-optically Q-switched Nd:LuVO4 crystal. The output…
The incidence of grey-observe might be measured by an increase of bulk absorption by a strong CW 532nm green laser within several minutes. This measurement can be executed with Picture-thermal Widespread-path interferometer.
