With this paper, the new lapping slurry and polishing slurry are introduced. As well as the deliquescence degree of CLBO is fallen to most affordable. A new Doing the job technologies is likewise adopted. Following rough polishing, the concentration of ultra-precision sharpening slurry is enhanced correctly. So does the ultra-precision polishing pace, as well as wiping velocity is faster when compared to the deliquescence speed. The CLBO crystal floor roughness can attain 1nm and retain the surface high-quality perfectly. Entry by way of your establishment

We summarized The existing growth status of your substantial-energy DUV laser both of those on the wavelength of FHG of the 1-μm laser and at 193 nm. The the latest progress of your stable-state/fiber laser, and also the nonlinear optical crystals, prompts not merely the average electric power but additionally the beam excellent (coherence) in the DUV lasers to an unparalleled stage.
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。

Due to thermal lens influence while in the strong-state lasers, In case the heating administration is inadequate, It isn't straightforward to obtain the good-point out laser having a significant electric power plus a higher beam good quality simultaneously. A short while ago, with the development of The skinny disk laser and single-crystal fiber (SCF) laser, a large-electric power laser at the fundamental wavelength (1 μm) had been recognized with a very good beam top quality even with a TEM00 method beam [four,24], which might be good candidates for the fundamental from the DUV laser generation. One more applicant for the fundamental may be the significant-ability fiber laser which might be attained by coherent beam combination with M2 value lower than 1.

The heart beat length of the 2nd Stokes light-weight was shortened to 5 ns as proven in Figure 7a, one-shot photograph with the oscilloscope, and that is a standard phenomenon in Raman laser [44] whilst the heartbeat duration from the pump check here laser was ten ns.
Furthermore, combining the good-state laser with other nonlinear system such as stimulated Raman scattering, NIR lasers can be attained at new wavelengths with superior electrical power and superior beam top quality, which was examined via the proof-of-theory experiment. This Raman laser scheme offers a whole new route to the large-electric power DUV laser, Primarily within the wavelength of 193 nm.
Tunable ultraviolet laser supply based upon stable-point out dye laser technological know-how and CsLiB6O10 harmonic technology
Its UV absorption edge reaches a hundred and eighty nm. The helpful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as huge as that of KDP. CLBO crystals could be developed through the stoichiometric melt with decrease viscosity.
