GAMDAN Optics hydrothermally grown KTP crystals Possess a substantially increased grey tracking resistance in comparison with flux grown KTP crystals.
KTP is a wonderful nonlinear crystal, but its grey monitoring phenomena limitations its use in higher repetition level and significant energy laser techniques. CASTECH's GTR-KTP crystal has higher grey monitoring resistance as opposed to normal flux developed KTP crystal.
The prevalence of gray-keep track of is often calculated by a boost of bulk absorption by a powerful CW 532nm environmentally friendly laser inside various minutes. This measurement may be done with Picture-thermal Common-path interferometer.
This Web page employs cookies to provide a number of our products and services together with for analytics and to supply you a more individualized knowledge.
Hugely successful intracavity frequency doubling 532-nm laser dependant on The grey tracking resistance KTP crystal
This check here phenomenon is correlated with “gray tracking influence�? The subsequent graphs demonstrate the absorption stage variations after some time at 1064 nm for CASTECH's GTR-KTP and the conventional KTP separately
Such crystals Have got a lower Original IR absorption and they are a lot less impacted by green gentle than normal KTP, thus avoid the issues of harmonic energy instabilities, performance drops, crystal blackening, and beam distortion.
Like our hydrothermally grown KTP crystals, flux developed KTP crystals also offer you exceptional homogeneity. Here are a few in their distinct parameters:
Significant grey tracking resistance, which makes it ideal for substantial repetition rate and large-ability laser methods.
To achieve entry to this material, remember to comprehensive the advice Sort and We are going to comply with up along with your librarian or Institution on the behalf.
Following air drying and subsequent cleaning having a cotton cloth soaked in alcohol, the movie area showed no signs of peeling or scratches.
Adhesion Take a look at Compliant with MIL-C-675C navy specifications, an adhesion test concerned implementing a tape that meets LT-ninety technical specs onto the lens film layer. The tape was affixed absolutely then eradicated vertically. This method was done thrice, resulting in no blistering or peeling.
