In this particular paper, The brand new lapping slurry and polishing slurry are introduced. And also the deliquescence diploma of CLBO is fallen to cheapest. A fresh Performing engineering is also adopted. After tough sprucing, the focus of ultra-precision sharpening slurry is greater effectively. So does the extremely-precision sprucing pace, as well as wiping speed is faster compared to deliquescence speed. The CLBO crystal area roughness can achieve 1nm and maintain the floor high quality well. Entry via your institution

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。
Conversely, the beam excellent of this increased energy DUV laser would turn into worse because of additional significant thermal and nonlinear effects. That's why, the frequency conversion processes must be diligently built to mitigate the aforementioned consequences. As a result, a significant-energy DUV laser in the FHG of one μm with an excellent beam excellent may be received and will be beneficial for obtaining the shorter wavelength DUV lasers for instance 193 nm by SFG.

On the other facet, the facility scaling of your NIR laser is yet another factor to raise the typical power of your 193-nm DUV laser. Due to the lack of the higher-energy amplification solution of your NIR laser (such as at 1553 nm), nonlinear frequency procedures for example optical parameter oscillation (OPO) could possibly be applied to establish a wavelength converter by shifting the wavelength from one μm to the desired wavelength in addition to acquiring relative larger energy [21]. Lately, a diamond Raman laser confirmed its capacity in attaining a high energy and a significant conversion effectiveness on the 1st Stokes from the one-μm laser [22,23], which implies the chance for being used from the 193-nm DUV laser generation due to its superior Raman get and large frequency change.

The heartbeat length of the 2nd Stokes gentle was shortened to 5 ns as revealed in Determine 7a, a single-shot photo in the oscilloscope, and that is a common phenomenon in Raman laser [44] although the pulse period in the pump laser was ten ns.
What's more, combining the sound-point out laser with other nonlinear process including stimulated Raman scattering, NIR lasers can be achieved at new wavelengths with large electricity and substantial beam top quality, which was examined by the evidence-of-theory experiment. This Raman laser plan provides a fresh route to the substantial-electric power DUV laser, Primarily within the wavelength of 193 nm.

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 big as that of KDP. CLBO crystals could be developed through the stoichiometric melt with decrease viscosity.
The event on the 193-nm laser was demonstrated by levels CLBO Crystal of SFG. In an effort to scale the DUV laser electrical power proficiently, a different idea from the 193-nm DUV laser technology is offered based on the diamond Raman laser.
