With this paper, The brand new lapping slurry and sprucing slurry are introduced. And also the deliquescence degree of CLBO is fallen to lowest. A whole new Doing the job engineering can be adopted. Just after tough sharpening, the concentration of ultra-precision sharpening slurry is enhanced properly. So does the ultra-precision polishing pace, as well as wiping velocity is quicker as opposed to deliquescence pace. The CLBO crystal floor roughness can reach 1nm and maintain the area top quality effectively. Access through your institution

We summarized The existing advancement position on the higher-electrical power DUV laser both for the wavelength of FHG of the one-μm laser and at 193 nm. The modern growth with the sound-point out/fiber laser, together with the nonlinear optical crystals, prompts not merely the average electrical power but will also the beam high quality (coherence) of the DUV lasers to an unparalleled degree.

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 the bigger electrical power DUV laser would come to be worse on account of a lot more really serious thermal and nonlinear effects. As a result, the frequency conversion procedures should be thoroughly made to mitigate the aforementioned results. So, a higher-electrical power DUV laser for the FHG of one μm with a good beam quality may be obtained and may be effective for getting the shorter wavelength DUV lasers including 193 nm by SFG.

The two the 1040 nm and 1078 click here nm laser come from one twin-wavelength Yb-doped fiber laser. Every single laser is amplified by stages of fiber amplifier and Yb-doped materials amplifier, respectively.

Just after payment, you'll obtain an email with instructions in addition to a url to download the ordered paper.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics from the Nd:YAG fundamental laser wavelength. In order to greatly enhance the problems threshold, lower CLBO surface area roughness, by extremely-precision machining, is required. Because the CLBO crystal has quick hydroscopic reaction and micro scratches in machining, extremely-precise machining on the CLBO crystal is really a complicated specialized problem.

The beam profile proven in Figure 7b demonstrated an excellent beam good quality as among the list of deserves of Raman laser, which might be useful to crank out a 193-nm DUV laser with a top quality beam.

Its UV absorption edge reaches one hundred eighty nm. The powerful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as huge as that of KDP. CLBO crystals might be grown with the stoichiometric melt with decrease viscosity.
