Potassium Titanyl Phosphate crystals (KTP) is The most greatly used nonlinear optical crystals in lots of optical techniques. GAMDAN Optics delivers GTR (grey monitoring resistant) KTP crystals which have been hydrothermally grown. We also provide flux developed KTP and can operate with our clients to provide probably the most appropriate Resolution in your application.
KTP is a superb nonlinear crystal, but its gray tracking phenomena limitations its use in large repetition charge and superior energy laser units. CASTECH's GTR-KTP crystal has bigger gray monitoring resistance in comparison to the regular flux developed KTP crystal.
Through Photo-thermal Frequent-route Interferometer, the occurrence of gray tracking is often calculated by a rise of bulk absorption via a strong CW 532 nm green laser inside of many minutes.
Q Precisely what is inexperienced semico... A At the moment, the Functioning theory of green semiconductor laser is to convert 1064nm infrared light emitted by infrared semiconductor laser into 532nm environmentally friendly mild by nonlinear crystallization. Gre
CASTECH's GRT-KTP, as a superb NLO crystal, has lessen absorption and higher problems threshold than the traditional KTP, which we can conclude it GTR-KTP Crystal possesses a better grey track resistance.
This phenomenon is correlated with “gray tracking effect�? The following graphs show the absorption level variations eventually at 1064 nm for CASTECH's GTR-KTP and the traditional KTP individually
These types of crystals have a reduced First IR absorption and so are significantly less impacted by inexperienced light than regular KTP, Consequently prevent the problems of harmonic power instabilities, effectiveness drops, crystal blackening, and beam distortion.
Like our hydrothermally developed KTP crystals, flux grown KTP crystals also present fantastic homogeneity. Here are some in their unique parameters:
Large gray tracking resistance, rendering it ideal for substantial repetition level and substantial-ability laser programs.
GTR-KTP crystals, designed with modern production procedures, exhibit noticeably better resistance to gray monitoring and decrease absorption from the UV and visual locations, generating them suited to a variety of apps like frequency doubling, parametric oscillation, and laser amplification.
