Potassium Titanyl Phosphate (KTiOPO4 or KTP) is an excellent nonlinear optical materials ideal for use in lots of optical units. It's got high nonlinear coefficient and stable physical home.
GTR-KTP crystal has gray observe resistance sufficiently bigger than regular flux-grown KTP. It's vast angular bandwidth and small stroll-off angle and wide temperature and spectral bandwidth. GTR-KTP crystals could be greatly Utilized in health care, armed forces and meteorology fields.

KTP is a superb nonlinear crystal, but its gray monitoring phenomena limitations its use in significant repetition amount and high electricity laser devices. CASTECH's GTR-KTP crystal has larger gray monitoring resistance in comparison to the typical flux developed KTP crystal.

Through Photograph-thermal Frequent-route Interferometer, the occurrence of gray monitoring may be calculated by a boost of bulk absorption through a robust CW 532 nm green laser inside of a number of minutes.
The pc you are employing just isn't registered by an institution with a subscription to this text. Remember to pick one of the options down below.
Its most favored software is as a frequency doubler utilizing the 1064nm output of the Nd:YAG laser and to deliver 532nm laser. KTP’s properties also allow it to be top-quality for electro-optic modulation, optical parametric era.
These crystals Have got a lower Preliminary IR absorption and they are less affected by environmentally friendly light-weight than common KTP, So stay clear of the issues of harmonic power instabilities, performance drops, crystal blackening, and beam distortion.
Remarkable problems click here threshold in comparison to conventional KTP crystals, guaranteeing reliability in demanding purposes.
The crystals are commonly utilized to double the frequency of Nd:YAG and Nd:YVO�?lasers, making seen inexperienced laser output (532 nm) from the basic 1064 nm wavelength.

Adhesion Examination Compliant with MIL-C-675C army requirements, an adhesion check concerned implementing a tape that meets LT-90 specifications onto the lens film layer. The tape was affixed thoroughly and then eradicated vertically. This procedure was carried out three times, resulting in no blistering or peeling.
Intracavity optical parametric oscillator at 1572-nm wavelength pumped by passively Q-switched diode-pumped Nd:YAG laser
