With this paper, the new lapping slurry and sharpening slurry are introduced. Plus the deliquescence degree of CLBO is fallen to least expensive. A different Operating know-how is usually adopted. Following rough polishing, the concentration of ultra-precision polishing slurry is greater thoroughly. So does the extremely-precision sharpening pace, as well as the wiping pace is quicker when compared to the deliquescence velocity. The CLBO crystal area roughness can achieve 1nm and preserve the surface high quality nicely. Entry through your institution

We summarized the current advancement status of your large-electric power DUV laser both of those on the wavelength of FHG on the one-μm laser and at 193 nm. The latest growth in the strong-point out/fiber laser, along with the nonlinear optical crystals, prompts not simply the normal power but will also the beam high-quality (coherence) of your 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。

Both equally the 1040 nm and 1078 nm laser originate from just one dual-wavelength Yb-doped fiber laser. Every laser is amplified by stages of fiber amplifier and Yb-doped products amplifier, respectively.

Also, combining the sound-point out laser with other nonlinear method which include stimulated Raman scattering, NIR lasers might be realized at new wavelengths with higher electric power and high beam top quality, which was examined via the evidence-of-principle experiment. This Raman laser scheme offers a whole new path to the significant-ability DUV laser, Specifically with the wavelength of 193 nm.

The conversion effectiveness get more info from fundamental NIR to DUV is from five% to 36% according to the reported ends in Table one. Escalating the conversion performance will reduce the stress on the design and setup of the elemental laser amplifier plus the electric powered electricity consumption. A superb beam quality of the basic laser can even add into the increasing in the conversion performance as well as the appropriate electrical power depth with the NIR and environmentally friendly laser in the SHG and FHG method, respectively. The very best conversion efficiencies from NIR to eco-friendly and eco-friendly to DUV laser by use of CLBO crystal are 70% and close to 50%, respectively [12], which corresponds to the conversion performance of 35% from elementary to DUV.
