Potassium Titanyl Phosphate (KTiOPO4 or KTP) is a wonderful nonlinear optical materials appropriate for use in several optical programs. It's got large nonlinear coefficient and secure Bodily property.

GTR-KTP crystal has gray monitor resistance sufficiently larger than usual flux-grown KTP. It has broad angular bandwidth and modest stroll-off angle and broad temperature and spectral bandwidth. GTR-KTP crystals might be commonly Utilized in clinical, military services and meteorology fields.

They are really produced at an optimally lower temperature that reduces the probability of defects, oxygen vacancies, crystal strains, or minimized metallic facilities.

KTP  is a wonderful nonlinear crystal, but its gray tracking phenomena  restrictions its use in substantial repetition rate and significant electrical power laser units. CASTECH's GTR-KTP crystal has larger grey monitoring resistance compared to common flux developed KTP crystal.

                                                                                                 

Via Photo-thermal Frequent-path Interferometer, the incidence of grey monitoring can be calculated by a boost of bulk absorption via a strong CW 532 nm green laser inside of many minutes.

This phenomenon is correlated with “gray tracking impact�? The following graphs display the absorption level modifications as time passes at 1064 nm for read more CASTECH's GTR-KTP and the conventional KTP independently          

The incidence of gray-track may be measured by a boost of bulk absorption by a powerful CW 532nm inexperienced laser in many minutes. This measurement could be carried out with Photo-thermal Popular-route interferometer.

Moreover, the shut autoclave expansion program allows for zero to minimum chemical impurities and also the continuous development price lends a great homogeneity or uniform yield through the bulk crystal. 

We present With this report an effective KTP-dependent intracavity optical parametric oscillator driven by a diode-pumped Nd:GdVO4/Cr:YAG passively Q-switched laser. For The very first time, a novel folded…

Adhesion Check Compliant with MIL-C-675C military services expectations, an adhesion test involved making use of a tape that satisfies LT-90 requirements on to the lens movie layer. The tape was affixed fully then eradicated vertically. This method was done thrice, causing no blistering or peeling.
