Within this paper, the new lapping slurry and sprucing slurry are launched. As well as deliquescence diploma of CLBO is fallen to cheapest. A different Performing know-how can be adopted. Right after tough sharpening, the concentration of extremely-precision sharpening slurry is amplified thoroughly. So does the ultra-precision sprucing speed, as well as wiping speed is quicker compared to deliquescence velocity. The CLBO crystal surface area roughness can realize 1nm and continue to keep the surface area quality properly. Obtain by means of your institution

We summarized The existing growth position on the large-ability DUV laser equally in the wavelength of FHG with the 1-μm laser and at 193 nm. The the latest growth of the reliable-point out/fiber laser, as well as the nonlinear optical crystals, prompts not merely the standard electric power and also the beam excellent (coherence) of the DUV lasers to an unparalleled level.
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 can be an excellent nonlinear crystal which is always applied to the SHG with the NIR towards the green. The DUV laser will likely be realized by two phases of SFG while in the LBO crystals since there's no stage-matching angle for LBO to convert the eco-friendly laser at 515 nm or 532 nm for the DUV right by SHG [16]. Not too long ago, the NSBBF crystal has also proven its likely to get a large conversion efficiency from 532 nm to 266 nm. The wander-off angle and deff with the NSBBF are Just about much like These of CLBO [seventeen].
On the opposite aspect, the power scaling of your NIR laser is yet another factor to raise the normal power of the 193-nm DUV laser. Mainly because of the insufficient the high-electric power amplification Remedy of the NIR laser (one example is at 1553 nm), nonlinear frequency processes for example optical parameter oscillation (OPO) may read more very well be applied to make a wavelength converter by shifting the wavelength from one μm to the desired wavelength and also getting relative better electrical power [21]. Not long ago, a diamond Raman laser confirmed its capacity in accomplishing a superior energy plus a significant conversion performance at the 1st Stokes of the 1-μm laser [22,23], which implies the possibility to be applied within the 193-nm DUV laser generation because of its high Raman acquire and enormous frequency change.

The development of the 193-nm laser was demonstrated by levels of SFG. To be able to scale the DUV laser electric power efficiently, a completely new notion with the 193-nm DUV laser generation is presented based upon the diamond Raman laser.
