Potassium Titanyl Phosphate (KTiOPO4 or KTP) is an excellent nonlinear optical product well suited for use in many optical units. It's higher nonlinear coefficient and secure physical assets.
Enhanced bulk absorption Qualities, cutting down IR absorption and improving All round optical effectiveness.
They can be produced at an optimally reduced temperature that reduces the likelihood of defects, oxygen vacancies, crystal strains, or decreased metal facilities.
KTP is an excellent nonlinear crystal, but its grey monitoring phenomena limitations its use in significant repetition price and significant energy laser devices. CASTECH's GTR-KTP crystal has higher gray monitoring resistance than the typical flux developed KTP crystal.
By way of Picture-thermal Prevalent-route Interferometer, the prevalence of grey monitoring is often calculated by a boost of bulk absorption via a solid CW 532 nm inexperienced laser in just quite a few minutes.

Really successful intracavity frequency doubling 532-nm laser according to the gray tracking resistance KTP crystal
This phenomenon is correlated with “grey monitoring outcome�? The subsequent graphs show the absorption stage changes eventually at 1064 nm for CASTECH's GTR-KTP and the standard KTP independently
Flux developed KTP crystals provide an even better selling price gain. It is usually simply fabricated in much larger Proportions.
Additionally, the shut autoclave advancement procedure permits zero to negligible chemical impurities and the continuous development price lends a superb homogeneity or uniform produce through the entire bulk crystal.
Likely of cancer screening with serum surface-Increased Raman spectroscopy and also a assist vector device

We report an intracavity optical parametric oscillator at one.57 μm based upon non-critically nonlinear crystal KTP driven by an close-pumped acousto-optically Q-switched Nd:LuVO4 crystal. The output…
