Potassium Titanyl Phosphate (KTiOPO4 or KTP) is a superb nonlinear optical product suited to use in many optical techniques. It has substantial nonlinear coefficient and stable physical house.
Enhanced bulk absorption Houses, minimizing IR absorption and strengthening General optical functionality.

KTP is a superb nonlinear crystal, but its grey monitoring phenomena boundaries its use in substantial repetition fee and high ability laser systems. CASTECH's GTR-KTP crystal has increased grey tracking resistance in comparison to the common flux developed KTP crystal.
Via Photo-thermal Prevalent-path Interferometer, the prevalence of grey tracking could be calculated by an increase of bulk absorption via a potent CW 532 nm green laser within just a number of minutes.
By way of Photograph-thermal Prevalent-route Interferometer, the prevalence of gray monitoring may be measured by a rise of bulk absorption via a powerful CW 532 nm environmentally friendly laser inside several minutes.

The event of grey-observe can be measured by an increase of bulk absorption by a solid CW 532nm environmentally friendly laser inside of several minutes. This measurement might be carried out with Image-thermal Widespread-path interferometer.
Like our hydrothermally grown KTP crystals, flux grown KTP crystals also offer fantastic homogeneity. Here are several of their specific parameters:
The crystals are generally accustomed to double the frequency of Nd:YAG and Nd:YVO�?lasers, producing visible environmentally friendly laser output (532 nm) from the basic 1064 nm wavelength.
GTR-KTP crystals, formulated with impressive production processes, show appreciably better resistance to gray tracking and lessen absorption in the UV and visual regions, making them suited to a variety of applications for example frequency doubling, parametric oscillation, and laser amplification.

Adhesion Check Compliant with MIL-C-675C armed forces standards, an adhesion examination concerned making use of website a tape that satisfies LT-90 requirements on to the lens film layer. The tape was affixed absolutely after which you can eliminated vertically. This treatment was executed thrice, resulting in no blistering or peeling.
Intracavity optical parametric oscillator at 1572-nm wavelength pumped by passively Q-switched diode-pumped Nd:YAG laser
