GTR-KTP crystals are extensively used in purposes that desire high-overall performance nonlinear optical supplies with improved durability and resistance to grey tracking. Some notable purposes consist of:

They can be created at an optimally very low temperature that minimizes the likelihood of defects, oxygen vacancies, crystal strains, or lessened steel centers.
KTP is a superb nonlinear crystal, but its grey tracking phenomena limits its use in large repetition amount and superior electric power laser methods. CASTECH's GTR-KTP crystal has increased gray tracking resistance in comparison to the common flux developed KTP crystal.
The event of grey-observe is usually measured by a boost of bulk absorption by a solid CW 532nm eco-friendly laser inside quite a few minutes. This measurement is often performed with Photo-thermal Common-path interferometer.

CASTECH's GRT-KTP, as a fantastic NLO crystal, has lessen absorption and higher damage threshold than the standard KTP, which we could conclude it possesses a greater grey keep track of resistance.

The incidence of gray-observe can be measured by a boost of bulk absorption by a strong CW 532nm inexperienced laser within several minutes. This measurement could be executed with Photo-thermal Frequent-path interferometer.
Like our hydrothermally grown KTP crystals, flux grown KTP crystals also provide great homogeneity. Here are a few of their distinct parameters:
The crystals are commonly accustomed to double the frequency of Nd:YAG and Nd:YVO�?lasers, producing noticeable inexperienced laser output (532 nm) from the elemental 1064 nm wavelength.

After air drying and subsequent cleansing with a cotton fabric soaked in Liquor, the film surface showed no indications of peeling or scratches.
Adhesion Test Compliant with MIL-C-675C armed forces standards, an adhesion check involved implementing a tape that meets LT-90 requirements onto the lens movie layer. The tape was affixed thoroughly and afterwards removed vertically. This method was performed 3 times, leading to no blistering or peeling.
