GTR-KTP Crystal - An Overview
Blog Article
Potassium Titanyl Phosphate (KTiOPO4 or KTP) is an excellent nonlinear optical substance well suited for use in lots of optical programs. It's high nonlinear coefficient and steady Bodily house.
GTR-KTP crystal has gray monitor resistance adequately bigger than common flux-grown KTP. It has huge angular bandwidth and little wander-off angle and broad temperature and spectral bandwidth. GTR-KTP crystals is usually widely Utilized in clinical, armed service and meteorology fields.
They are produced at an optimally very low temperature that minimizes the probability of defects, oxygen vacancies, crystal strains, or lessened steel centers.
A compact economical eye-Risk-free intracavity optical parametric oscillator pumped by a passively Q-switched Nd:YAG laser in a shared cavity configuration with productive conversion efficiency as higher as fifty one% is introduced.
As a result of Photograph-thermal Prevalent-route Interferometer, the event of grey tracking is usually calculated by an increase of bulk absorption via a potent CW 532 nm environmentally friendly laser within just quite a few minutes.

This phenomenon is correlated with “grey monitoring outcome�? The following graphs display the absorption degree improvements as time passes at 1064 nm for CASTECH's GTR-KTP and the traditional KTP independently
This kind of crystals Have a very lessen Original IR absorption and therefore are considerably less impacted by green light-weight than typical KTP, Hence stay away from the problems of harmonic electrical power instabilities, efficiency drops, crystal blackening, and beam distortion.
Moreover, the closed autoclave progress program permits zero to negligible chemical impurities along with the constant growth charge lends a fantastic homogeneity or uniform produce all over the bulk crystal.
We existing Within this report an effective KTP-based intracavity optical parametric oscillator driven by a diode-pumped Nd:GdVO4/Cr:YAG passively Q-switched laser. For The 1st time, a novel folded…
GTR-KTP crystals, made with modern producing procedures, exhibit noticeably bigger resistance to grey tracking and decreased absorption within the UV and visual areas, creating them appropriate for a wide range of purposes for instance frequency doubling, parametric oscillation, and laser amplification.
To achieve access to this information, make sure you comprehensive the Recommendation Form and We are going to comply with up with the librarian or Institution on your own behalf.
Adhesion Test Compliant with MIL-C-675C military services criteria, an adhesion exam concerned implementing a tape that satisfies LT-ninety requirements on to the lens film layer. The tape was affixed thoroughly after which eradicated vertically. This method was performed three times, causing no blistering or peeling.
With their broad spectral assortment click here and small IR absorption, GTR-KTP crystals are well-suited for spectroscopic devices and Superior imaging technologies.
