In this particular paper, the new lapping slurry and sharpening slurry are launched. As well as deliquescence degree of CLBO is fallen to least expensive. A fresh Functioning technological innovation is likewise adopted. Just after rough sharpening, the focus of ultra-precision sharpening slurry is greater adequately. So does the extremely-precision polishing speed, and also the wiping pace is faster compared to deliquescence velocity. The CLBO crystal floor roughness can accomplish 1nm and preserve the surface quality properly. Entry by way of your establishment

We summarized The existing growth position in the high-electricity DUV laser both equally at the wavelength of FHG of your 1-μm laser and at 193 nm. The latest progress of your solid-condition/fiber laser, together with the nonlinear optical crystals, prompts don't just the standard power but also the beam quality (coherence) of the DUV lasers to an unparalleled stage.
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。

Equally the 1040 nm and 1078 nm laser come from one twin-wavelength Yb-doped fiber laser. Every laser is amplified by levels of fiber amplifier and Yb-doped materials amplifier, respectively.
On another side, the facility scaling with the NIR laser is an additional aspect to improve the common power with the 193-nm DUV laser. As a result of insufficient the high-electric power amplification Resolution from the NIR laser (one example is at 1553 nm), nonlinear frequency procedures such as optical parameter oscillation (OPO) could possibly be applied to produce a wavelength converter by shifting the wavelength from one μm to the specified wavelength and getting relative higher electrical power [21]. Recently, a diamond Raman laser confirmed its ability in accomplishing a superior electrical power and also a high conversion effectiveness within the 1st Stokes on the one-μm laser [22,23], which means the chance to be applied inside the 193-nm DUV laser era as a consequence of its significant Raman attain and large frequency shift.

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 can be grown from the stoichiometric melt with lessen viscosity.
The development on the 193-nm laser was shown by stages of SFG. In an effort to scale the DUV laser power efficiently, a completely new principle from the 193-nm DUV laser technology is presented determined by the diamond Raman laser.
