A Simple Key For GTR-KTP Crystal Unveiled
Blog Article
GTR-KTP crystals are broadly used in applications that desire higher-performance nonlinear optical products with improved sturdiness and resistance to gray tracking. Some noteworthy purposes consist of:
Subject areas might be refined more within the search results. The subject aspect will reveal the high-degree matters connected with the article content returned inside the search engine results. Specific COLLECTIONS
They are really created at an optimally very low temperature that lowers the likelihood of defects, oxygen vacancies, crystal strains, or decreased metal facilities.
KTP is a superb nonlinear crystal, but its grey tracking phenomena boundaries its use in large repetition amount and superior energy laser programs. CASTECH's GTR-KTP crystal has larger gray monitoring resistance than the regular flux developed KTP crystal.
The event of grey-track is usually measured by an increase of bulk absorption by a solid CW 532nm inexperienced laser within a number of minutes. This measurement may be done with Picture-thermal Prevalent-path interferometer.

CASTECH's GRT-KTP, as a great NLO crystal, has reduce absorption and higher destruction threshold than the traditional KTP, which we will conclude it possesses a higher gray track resistance.
Its most popular software is as a frequency doubler making use of the 1064nm output of a Nd:YAG laser and to generate 532nm laser. KTP’s Qualities also allow it to be top-quality for electro-optic modulation, optical parametric era.
The event of gray-track might be calculated by a boost of bulk absorption by a powerful CW 532nm inexperienced laser inside of a number of minutes. This measurement is usually executed with Picture-thermal Widespread-path interferometer.
Top-quality hurt threshold in comparison to standard KTP crystals, guaranteeing reliability in demanding programs.
The crystals are generally used to double here the frequency of Nd:YAG and Nd:YVO�?lasers, producing seen environmentally friendly laser output (532 nm) from the basic 1064 nm wavelength.

Adhesion Check Compliant with MIL-C-675C army specifications, an adhesion check involved making use of a tape that meets LT-90 specs on to the lens movie layer. The tape was affixed fully then taken off vertically. This technique was done thrice, leading to no blistering or peeling.
