With this paper, The brand new lapping slurry and polishing slurry are launched. Along with the deliquescence diploma of CLBO is fallen to most affordable. A completely new Functioning technology is likewise adopted. Following rough sprucing, the focus of ultra-precision polishing slurry is improved appropriately. So does the ultra-precision polishing speed, as well as the wiping speed is quicker compared to deliquescence velocity. The CLBO crystal area roughness can reach 1nm and keep the surface high quality effectively. Accessibility by way of your establishment

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。
On the other hand, the beam high quality of the higher energy DUV laser would become worse due to a lot more really serious thermal and nonlinear effects. Consequently, the frequency conversion processes really should be carefully made to mitigate the aforementioned consequences. Thus, a substantial-electrical power DUV laser within the FHG of 1 μm with a great beam good quality can be obtained and will be advantageous for getting the shorter wavelength DUV lasers which include 193 nm by SFG.
As a result of thermal lens impact inside the strong-state lasers, Should the heating administration is insufficient, It's not at all quick to get the strong-condition laser which has a substantial electrical power and a significant beam high quality concurrently. Lately, with the development of The skinny disk laser and one-crystal fiber (SCF) laser, a higher-electricity laser at the elemental wavelength (one μm) were understood with a superb beam quality Despite a TEM00 manner beam [four,24], which might be excellent candidates for the basic with the DUV laser technology. An additional applicant for the fundamental may be the substantial-electricity fiber laser which could possibly be realized by coherent beam blend with M2 price below 1.

During the scientific and industrial purposes, the beam excellent with the DUV laser is usually a very important parameter. Significantly, the beam high-quality on the DUV laser substantially impacts the laser machining results. The beam high-quality on the DUV laser is determined by that of the elemental laser and the crystal for your frequency conversion. Recently, a high-electric power DUV laser (>10 W) at 258 nm was claimed by using a beam high quality of M2 < one.five, which was generated by FHG of the Yb:YAG laser at 1030 nm utilizing the CLBO crystal [13]. This laser would bring on a greater laser machining outcome in comparison with the past DUV lasers with larger M2.

Tunable ultraviolet laser source based on solid-condition dye laser technological innovation and CsLiB6O10 harmonic technology
Its UV absorption edge reaches one hundred eighty nm. The successful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about twice as huge as that of KDP. CLBO crystals might be developed from your stoichiometric melt with decreased viscosity.
