In this particular paper, the new lapping slurry and sharpening slurry are released. As well as the deliquescence degree of CLBO is fallen to cheapest. A fresh Doing the job engineering can be adopted. Immediately after tough sprucing, the focus of extremely-precision sharpening slurry is improved adequately. So does the extremely-precision sharpening speed, as well as the wiping pace is faster in comparison to the deliquescence velocity. The CLBO crystal floor roughness can reach 1nm and hold the area top quality perfectly. Entry by your establishment

Based on the proof-of-basic principle experiment, the conversion performance of 23% implied the opportunity of achieving large-electricity at the second Stokes wavelength from the Raman laser. If the pump laser of 1078 nm could be obtained at the standard electricity of 50 W, the output electric power of its 2nd Stokes wavelength at 1512 nm may be greater than ten W. The design in the Raman laser cavity ought to be optimized in an effort to avoid the hurt of the M1 and diamond surface area.
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。

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the most effective non-linear crystal which generates ultraviolet harmonics of your Nd:YAG elementary laser wavelength. In an effort to improve the damage threshold, lower CLBO surface roughness, by extremely-precision machining, is needed. As the CLBO crystal has quick hydroscopic reaction and micro scratches in machining, ultra-specific machining with the CLBO crystal is actually a tough technological difficulty.
The beam profile shown in Figure 7b demonstrated an excellent beam excellent as one of the deserves of Raman laser, which might be advantageous to create a 193-nm DUV laser with a high quality beam.
Its UV absorption edge reaches a hundred and eighty nm. The efficient nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as large as that of KDP. CLBO crystals could be grown from the stoichiometric soften with decreased viscosity.
