GTR-KTP crystals are extensively used in purposes that demand from customers high-functionality nonlinear optical elements with enhanced toughness and resistance to grey tracking. Some noteworthy apps include things like:
GTR-KTP crystal has grey keep track of resistance adequately bigger than standard flux-grown KTP. It's large angular bandwidth and little walk-off angle and broad temperature and spectral bandwidth. GTR-KTP crystals could be broadly Utilized in clinical, military services and meteorology fields.
They are really created at an optimally lower temperature that reduces the probability of defects, oxygen vacancies, crystal strains, or diminished steel facilities.
KTP is a superb nonlinear crystal, but its grey tracking phenomena boundaries its use in higher repetition amount and higher electric power laser methods. CASTECH's GTR-KTP crystal has better grey tracking resistance in comparison to the regular flux grown KTP crystal.
By way of Photograph-thermal Frequent-route Interferometer, the prevalence of gray monitoring is often measured by an increase of bulk absorption via a robust CW 532 nm green laser inside of quite a few minutes.

The event of grey-keep track of might be calculated by an increase of bulk absorption by a powerful CW 532nm environmentally friendly laser inside many minutes. This measurement is usually done with Image-thermal Typical-path interferometer.
Like our hydrothermally developed KTP crystals, flux grown KTP crystals also provide superb homogeneity. Here are some in their certain parameters:
Substantial grey monitoring resistance, making it ideal for superior repetition price and substantial-electrical power laser units.
GTR-KTP crystals, made with impressive production procedures, show considerably higher resistance to grey monitoring and decrease absorption from the UV and visible locations, generating them well suited for a wide array of applications such as frequency doubling, parametric oscillation, and laser amplification.

Adhesion Exam Compliant more info with MIL-C-675C navy requirements, an adhesion test included making use of a tape that fulfills LT-ninety requirements onto the lens movie layer. The tape was affixed fully and after that eradicated vertically. This procedure was carried out 3 times, leading to no blistering or peeling.
With their wide spectral array and small IR absorption, GTR-KTP crystals are very well-fitted to spectroscopic devices and Highly developed imaging systems.
