GTR-KTP crystals are extensively utilized in applications that demand from customers significant-effectiveness nonlinear optical resources with enhanced durability and resistance to gray monitoring. Some noteworthy programs include things like:

Increased bulk absorption properties, minimizing IR absorption and improving upon General optical functionality.

They may be produced at an optimally low temperature that cuts down the probability of defects, oxygen vacancies, crystal strains, or lowered steel centers.

KTP  is a superb nonlinear crystal, but its grey tracking phenomena  boundaries its use in higher repetition amount and substantial energy laser techniques. CASTECH's GTR-KTP crystal has greater grey monitoring resistance when compared to the frequent flux grown KTP crystal.

The prevalence of grey-observe can be calculated by a boost of bulk absorption by a powerful CW 532nm eco-friendly laser within just several minutes. This measurement can be performed with Picture-thermal Typical-path interferometer.

Remarkably productive intracavity frequency doubling 532-nm laser determined by the gray monitoring resistance KTP crystal

                                                                                                 

These types of crystals Use a reduced Original IR absorption and they are get more info much less influenced by eco-friendly light than regular KTP, Therefore keep away from the problems of harmonic electrical power instabilities, performance drops, crystal blackening, and beam distortion.

Like our hydrothermally grown KTP crystals, flux grown KTP crystals also give great homogeneity. Here are several in their unique parameters: 

Superior grey tracking resistance, which makes it ideal for substantial repetition amount and higher-ability laser devices.

GTR-KTP crystals, created with revolutionary manufacturing processes, exhibit substantially larger resistance to grey monitoring and decreased absorption during the UV and visual areas, producing them suitable for a variety of apps for example frequency doubling, parametric oscillation, and laser amplification.
