With this paper, The brand new lapping slurry and sprucing slurry are launched. As well as deliquescence degree of CLBO is fallen to most affordable. A whole new Performing technological know-how is additionally adopted. Right after tough sprucing, the concentration of ultra-precision polishing slurry is improved correctly. So does the ultra-precision sprucing speed, along with the wiping velocity is faster compared to the deliquescence velocity. The CLBO crystal surface area roughness can achieve 1nm and preserve the surface area top quality properly. Entry via your institution

According to the proof-of-principle experiment, the conversion effectiveness of 23% implied the opportunity of attaining superior-electrical power at the 2nd Stokes wavelength on the Raman laser. When the pump laser of 1078 nm can be acquired at the standard electricity of fifty W, the output electrical power of its 2nd Stokes wavelength at 1512 nm can be more than 10 W. The design on the Raman laser cavity really should be optimized in order to avoid the damage with the M1 and diamond surface.
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。

In the scientific and industrial programs, the beam top quality on the DUV laser is likewise a very important parameter. Specially, the beam quality with the DUV laser substantially affects the laser machining results. The beam high-quality with the DUV laser is determined by that of the basic laser as well as the crystal for that frequency conversion. Not too long ago, a high-electric power DUV laser (>ten W) at 258 nm was noted with a beam excellent of M2 < 1.5, which was created by FHG of a Yb:YAG laser at 1030 nm using the CLBO crystal [thirteen]. This laser would result in an even better laser machining outcome in comparison to the past DUV lasers with larger M2.
