On this paper, the new lapping slurry and sharpening slurry are launched. As well as deliquescence diploma of CLBO is fallen to cheapest. A completely new working technologies is additionally adopted. Soon after rough polishing, the concentration of ultra-precision polishing slurry is elevated effectively. So does the ultra-precision polishing pace, as well as the wiping speed is quicker when compared to the deliquescence velocity. The CLBO crystal area roughness can obtain 1nm and preserve the surface area high quality well. Access by your establishment

In accordance with the proof-of-basic principle experiment, the conversion effectiveness of 23% implied the potential of accomplishing superior-electrical power at the second Stokes wavelength with the Raman laser. In the event the pump laser of 1078 nm can be acquired at the normal electric power of fifty W, the output electrical power of its 2nd Stokes wavelength at 1512 nm could possibly be much more than 10 W. The look with the Raman laser cavity must be optimized to be able to stay away from the injury of your M1 and diamond floor.
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。

LBO is usually an excellent nonlinear crystal which is always placed on the SHG with the NIR for the environmentally friendly. The DUV laser is usually recognized by two levels of SFG within the LBO crystals due to the fact there isn't any stage-matching angle for LBO to transform the environmentally friendly laser at 515 nm or 532 nm to the DUV immediately by SHG [16]. A short while ago, the NSBBF crystal has also shown its prospective to obtain a higher conversion performance from 532 nm to 266 nm. The stroll-off angle and deff on the NSBBF are Pretty much just like These of CLBO [17].

Inside the scientific and industrial apps, the beam top quality in the DUV laser can be a vital parameter. Specially, the beam excellent with the DUV laser considerably influences the laser machining effects. The beam excellent with the DUV laser is decided by that of the basic laser along with the crystal to the frequency conversion. Not too long ago, a higher-energy DUV laser (>ten W) at 258 nm was documented using a beam top quality of M2 website < 1.five, which was created by FHG of a Yb:YAG laser at 1030 nm using the CLBO crystal [thirteen]. This laser would bring on a greater laser machining consequence when compared with the earlier DUV lasers with bigger M2.

Furthermore, combining the sound-condition laser with other nonlinear system such as stimulated Raman scattering, NIR lasers could possibly be realized at new wavelengths with superior energy and higher beam excellent, which was analyzed by the proof-of-principle experiment. This Raman laser plan supplies a different path to the superior-ability DUV laser, especially at the wavelength of 193 nm.
Tunable ultraviolet laser source based upon solid-condition dye laser technology and CsLiB6O10 harmonic era
Its UV absorption edge reaches a hundred and eighty nm. The effective nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as significant as that of KDP. CLBO crystals may be grown with the stoichiometric soften with lessen viscosity.
