CLBO Crystal Secrets

On this paper, the new lapping slurry and polishing slurry are introduced. Plus the deliquescence degree of CLBO is fallen to least expensive. A fresh Doing the job technological know-how is likewise adopted. After tough sprucing, the focus of extremely-precision sharpening slurry is improved thoroughly. So does the ultra-precision sharpening pace, and also the wiping speed is faster when compared to the deliquescence speed. The CLBO crystal surface area roughness can accomplish 1nm and retain the surface quality nicely. Access by means of your establishment

We summarized The present enhancement position on the high-power DUV laser the two for the wavelength of FHG from the 1-μm laser and at 193 nm. The latest development of the stable-point out/fiber laser, along with the nonlinear optical crystals, prompts not simply the typical ability and also the beam good quality (coherence) with the DUV lasers to an unprecedented degree.

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。

On one other side, the ability scaling of your NIR laser is another factor to increase the average electricity in the 193-nm DUV laser. Because of the insufficient the superior-energy amplification Alternative from the NIR laser (one example is at 1553 nm), nonlinear frequency procedures such as optical parameter oscillation (OPO) could possibly be placed on make a wavelength converter by shifting the wavelength from one μm to the desired wavelength and also getting relative higher electricity [21]. Not too long ago, a diamond Raman laser showed its potential in acquiring a large energy and a superior conversion performance on the 1st Stokes from the one-μm laser [22,23], which suggests the chance to generally be used inside the 193-nm DUV laser generation as a consequence of its large Raman attain and enormous frequency change.

Tunable ultraviolet laser supply depending on solid-condition dye laser engineering and CsLiB6O10 harmonic technology

The conversion efficiency from fundamental NIR to DUV is from 5% to 36% based on the noted brings about Table one. Raising the conversion performance will decrease the load on the design and setup of the basic laser amplifier along with the electric electricity intake. A fantastic beam high-quality of the elemental laser will also add for the increasing of the conversion performance in addition to the appropriate energy depth on the NIR and eco-friendly laser within the SHG and FHG process, respectively. The highest conversion efficiencies from NIR to environmentally friendly and green to DUV here laser by use of CLBO crystal are 70% and all-around fifty%, respectively [12], which corresponds towards the conversion efficiency of 35% from elementary to DUV.
