KTP is a superb nonlinear crystal, but its gray tracking phenomena boundaries its use in superior repetition level and significant electrical power laser units. CASTECH's GTR-KTP crystal has increased gray monitoring resistance compared to the normal flux developed KTP crystal.

Via Picture-thermal Popular-path Interferometer, the occurrence of grey monitoring can be calculated by an increase of bulk absorption by way of a potent CW 532 nm green laser within various minutes.
CASTECH's GRT-KTP, as a great NLO crystal, has lower absorption and higher hurt threshold than the conventional KTP, which we could conclude it possesses a higher grey observe resistance.

The event of grey-monitor can be measured by a rise of bulk absorption by a strong CW 532nm environmentally friendly laser inside of several minutes. This measurement is usually executed with Picture-thermal Common-route interferometer.
Like our hydrothermally developed KTP crystals, flux grown KTP crystals also supply outstanding homogeneity. Below are a few of their precise parameters:
Substantial gray monitoring resistance, making it ideal for significant repetition price and substantial-electric power laser devices.
GTR-KTP crystals, produced with innovative production procedures, show drastically higher resistance to grey monitoring and decrease absorption inside the UV and visual areas, building them ideal for an array of programs for instance frequency doubling, parametric oscillation, and laser amplification.
After air drying and subsequent cleansing having a cotton fabric soaked in Liquor, the movie surface area confirmed no signs of peeling or scratches.
Highly developed producing procedures guaranteeing Excellent gray monitoring resistance and optical Homes.
