Potassium Titanyl Phosphate (KTiOPO4 or KTP) is a wonderful nonlinear optical content suited to use in several optical techniques. It's got large nonlinear coefficient and secure physical home.
Comparison amongst shared and coupled resonators for passively Q-switched Nd:GdVO4 intracavity optical parametric oscillators
GAMDAN Optics hydrothermally grown KTP crystals Use a significantly bigger grey monitoring resistance as compared to flux grown KTP crystals.
KTP is an excellent nonlinear crystal, but its grey monitoring phenomena boundaries its use in higher repetition price and higher electrical power laser techniques. CASTECH's GTR-KTP crystal has better grey monitoring resistance compared to regular flux developed KTP crystal.

Remarkably effective intracavity frequency doubling 532-nm laser based on the gray monitoring resistance KTP crystal
This phenomenon is correlated with “grey tracking impact�? The subsequent graphs display the absorption level changes as time passes at 1064 nm for CASTECH's GTR-KTP and the conventional KTP separately
The event of grey-track is usually calculated by an increase of bulk absorption by a powerful CW 532nm green laser within just quite a few minutes. This measurement could be performed with Photograph-thermal Prevalent-path interferometer.
Like our hydrothermally developed KTP crystals, flux grown KTP crystals also offer superb homogeneity. Here are some in their distinct parameters:
Substantial grey monitoring resistance, making it perfect for higher repetition charge and superior-ability laser methods.
GTR-KTP crystals, produced with innovative producing procedures, show appreciably better resistance to gray monitoring and reduce absorption here in the UV and visual regions, building them ideal for a wide range of programs such as frequency doubling, parametric oscillation, and laser amplification.

Adhesion Take a look at Compliant with MIL-C-675C armed service specifications, an adhesion check included implementing a tape that fulfills LT-90 technical specs on to the lens film layer. The tape was affixed thoroughly and after that removed vertically. This procedure was performed three times, leading to no blistering or peeling.
