The Ultimate Guide To CLBO Crystal
The Ultimate Guide To CLBO Crystal
Blog Article
With this paper, the new lapping slurry and sharpening slurry are launched. Plus the deliquescence degree of CLBO is fallen to most affordable. A fresh Doing work technological know-how can be adopted. Just after tough polishing, the concentration of extremely-precision sharpening slurry is elevated effectively. So does the extremely-precision polishing pace, as well as wiping pace is faster when compared to the deliquescence pace. The CLBO crystal surface roughness can reach 1nm and preserve the floor top quality properly. Access by way of your institution
When compared with BBO it characteristics larger spectral and temperature acceptance, better angle tolerance, plus a more compact wander-off angle. from 3289 $ delivery

全固态紫外激光器以其体积小、寿命长、效率高、光束质量好、调谐范围宽、谱线窄等优点，广泛应用于机械探伤、光刻、微加工和医学等领域，等，利用大功率近红外相干光源作为基于非线性调谐技术的基频源，通过多级变频产生紫外相干辐射被认为是发展紫外相干光源的重要途径。紫外相干光源的关键问题是研制紫外波段的非线性光学变频晶体。非线性光学晶体是实现频率变换的条件之一，因此对非线性光学晶体的生长、尺寸、损伤电阻、转换效率和允许的参数范围提出了越来越高的要求。
Then again, the beam high-quality of this bigger electric power DUV laser would grow to be worse as a consequence of much more severe thermal and nonlinear results. Hence, the frequency conversion procedures needs to be cautiously built to mitigate the aforementioned results. As a result, a superior-ability DUV laser on the FHG of one μm with a good beam high quality could possibly be obtained and will be advantageous for acquiring the shorter wavelength DUV lasers such as 193 nm by SFG.
LBO is likewise a wonderful nonlinear crystal which is often applied to the SHG within the NIR towards the eco-friendly. The DUV laser is usually understood by two phases of SFG in the LBO crystals considering the fact that there isn't a stage-matching angle for LBO to convert the eco-friendly laser at 515 nm or 532 nm towards the DUV straight by SHG [sixteen]. Not too long ago, the NSBBF crystal has also proven its likely to obtain a large conversion efficiency from 532 nm to 266 nm. The wander-off angle and deff on the NSBBF are Nearly comparable to All those of CLBO [17].

The conversion efficiency from fundamental NIR to DUV is from five% to 36% in accordance with the documented brings about Desk one. Escalating the conversion effectiveness will reduce the burden on the look and set up of the elemental laser amplifier plus the electric energy intake. A superb beam top quality of the basic laser will also contribute on the rising with more info the conversion performance in addition to the suitable power intensity of the NIR and inexperienced laser in the SHG and FHG procedure, respectively. The very best conversion efficiencies from NIR to green and environmentally friendly to DUV laser by usage of CLBO crystal are 70% and around fifty%, respectively [twelve], which corresponds into the conversion effectiveness of 35% from essential to DUV.
