In this particular paper, The brand new lapping slurry and polishing slurry are released. And the deliquescence degree of CLBO is fallen to least expensive. A brand new Doing the job engineering is also adopted. Right after rough sharpening, the concentration of ultra-precision sharpening slurry is greater properly. So does the ultra-precision polishing speed, and the wiping speed is faster compared to the deliquescence speed. The CLBO crystal area roughness can reach 1nm and retain the floor high quality well.

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。

The two the 1040 nm and 1078 nm laser originate from one particular dual-wavelength Yb-doped fiber laser. Every single laser is amplified by stages of fiber amplifier and Yb-doped resources amplifier, respectively.
On the opposite aspect, the power scaling of the NIR laser is yet another factor to raise the normal electricity in the 193-nm DUV laser. Because of the not enough the large-power amplification solution in the NIR laser (for instance at 1553 nm), nonlinear frequency procedures for instance optical parameter oscillation (OPO) may be placed on make a wavelength converter by shifting the wavelength from 1 μm to the desired wavelength together with obtaining relative increased power [21]. Not long ago, a diamond Raman laser confirmed its ability in attaining a significant power and a significant conversion efficiency at the 1st Stokes with the 1-μm laser [22,23], which suggests the possibility to become applied inside the 193-nm DUV laser era due to its high Raman gain and large frequency change.

The heart beat period of the 2nd Stokes mild was shortened to five ns as revealed in Figure 7a, one-shot picture with the oscilloscope, which is a typical phenomenon in Raman laser [44] when the heart beat duration in the pump laser was 10 ns.

The beam profile proven in Figure 7b demonstrated an excellent beam good quality as among the list of merits of Raman laser, which would be advantageous to produce a 193-nm DUV laser with a high quality beam.
Its UV absorption edge reaches one hundred eighty nm. The efficient nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as huge as that of KDP. CLBO crystals could be grown from the stoichiometric melt with decreased viscosity.
