GTR-KTP crystals are widely utilized in programs that need significant-performance nonlinear optical products with enhanced sturdiness and resistance to gray monitoring. Some notable applications include:

GTR-KTP crystal has gray observe resistance adequately higher than regular flux-grown KTP. It has huge angular bandwidth and little stroll-off angle and wide temperature and spectral bandwidth. GTR-KTP crystals can be broadly Employed in medical, armed forces and meteorology fields.

KTP  is an excellent nonlinear crystal, but its gray monitoring phenomena  restrictions its use in substantial repetition price and substantial electrical power laser techniques. CASTECH's GTR-KTP crystal has increased grey tracking resistance as opposed to typical flux developed KTP crystal.

                                                                                                 

Through Photograph-thermal Common-path Interferometer, the prevalence of grey tracking might be measured by a boost of bulk absorption via a solid CW 532 nm green laser in various minutes.

CASTECH's GRT-KTP, as a superb NLO crystal, has reduce absorption and better problems threshold than the standard KTP, which we are able to conclude it possesses a higher grey monitor resistance.

The incidence of grey-monitor can be calculated by a boost of bulk absorption by a strong CW 532nm inexperienced laser inside of quite a few minutes. This measurement may be done with Photograph-thermal Popular-path interferometer.

Also, the shut autoclave progress process permits zero to small chemical impurities as well as regular advancement level lends an excellent homogeneity or uniform generate through the bulk crystal. 

High grey tracking resistance, rendering it ideal for high repetition amount and large-energy laser units.
