A compact efficient eye-Harmless intracavity optical parametric oscillator pumped by a passively Q-switched Nd:YAG laser inside of a shared cavity configuration with efficient conversion efficiency as high as fifty one% is introduced.
The event of gray-observe is often measured by a rise of bulk absorption by a robust CW 532nm eco-friendly laser in just several minutes. This measurement is often performed with Photograph-thermal Frequent-path interferometer.
By way of Photograph-thermal Common-path Interferometer, the occurrence of gray monitoring could be measured by an increase of bulk absorption by way of a potent CW 532 nm inexperienced laser inside of many minutes.
Really effective intracavity frequency doubling 532-nm laser based upon The grey tracking resistance KTP crystal
This phenomenon is correlated with “grey monitoring influence�? The subsequent graphs show the absorption level modifications with time at 1064 nm for CASTECH's GTR-KTP and the traditional KTP individually
KTP is a superb nonlinear crystal, but its gray monitoring phenomena boundaries its use in large repetition price and high ability laser programs. CASTECH's GTR-KTP crystal has larger grey tracking resistance compared to regular flux developed KTP crystal.
On top of that, the closed autoclave progress technique permits zero to small chemical impurities plus the regular advancement level lends an excellent homogeneity or uniform yield all over the bulk crystal.
We current Within this report an efficient KTP-dependent intracavity optical parametric oscillator driven by a diode-pumped Nd:GdVO4/Cr:YAG passively Q-switched laser. For the first time, a novel folded…
GTR-KTP crystals, created with ground breaking producing procedures, show substantially larger resistance to gray monitoring and lower absorption inside the UV and visual locations, making them appropriate for a wide array of purposes like frequency doubling, parametric oscillation, and laser amplification.
CASTECH's GRT-KTP, as a great NLO crystal, has reduce absorption and higher injury threshold than the traditional KTP, which we will conclude it possesses a better gray monitor resistance. Variety of views:
State-of-the-art production processes making sure Fantastic gray tracking resistance and optical Attributes.
The occurrence of grey-observe is usually measured by a rise of bulk absorption by a powerful CW 532nm environmentally friendly laser within numerous minutes. This measurement is often executed with more info Photo-thermal Typical-path interferometer.
