The Definitive Guide to CLBO Crystal
Blog Article
With this paper, The brand new lapping slurry and sharpening slurry are released. As well as deliquescence degree of CLBO is fallen to most affordable. A different working technological innovation is usually adopted. After rough polishing, the focus of extremely-precision sharpening slurry is amplified properly. So does the extremely-precision sharpening pace, along with the wiping pace is faster compared to deliquescence pace. The CLBO crystal floor roughness can accomplish 1nm and maintain the surface high-quality perfectly. Entry by way of 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。

Due to thermal lens result inside the strong-point out lasers, If your heating management is inadequate, It's not at all simple to acquire the sound-point out laser using a high electricity along with a large beam high quality at the same time. Not too long ago, with the event of The skinny disk laser and one-crystal fiber (SCF) laser, a large-electric power laser at the elemental wavelength (1 μm) had been realized with a superb beam high-quality even with a TEM00 mode beam [4,24], which might be superior candidates for the elemental from the DUV laser generation. Yet another candidate for the fundamental may be the substantial-electricity fiber laser which may very well be realized by coherent beam blend with M2 worth under 1.

In the scientific and industrial purposes, the beam quality of the DUV laser is also an important parameter. Significantly, the beam excellent on the DUV laser considerably influences the laser machining outcomes. The beam quality with the DUV laser is set by that of the elemental laser along with the crystal for your frequency conversion. A short while ago, a substantial-electrical power DUV laser (>ten W) at 258 nm was noted that has a beam high quality of M2 < one.five, which was created by FHG of the Yb:YAG laser at 1030 nm using the CLBO crystal [13]. CLBO Crystal This laser would produce a much better laser machining consequence in comparison to the preceding DUV lasers with larger sized M2.

The conversion performance from basic NIR to DUV is from five% to 36% based on the reported ends in Table 1. Increasing the conversion performance will reduce the stress on the design and setup of the elemental laser amplifier plus the electric powered electricity use. An excellent beam high-quality of the fundamental laser can even add towards the rising of your conversion efficiency along with the suitable electric power depth of your NIR and green laser within the SHG and FHG method, respectively. The very best conversion efficiencies from NIR to eco-friendly and eco-friendly to DUV laser by use of CLBO crystal are 70% and close to 50%, respectively [12], which corresponds towards the conversion efficiency of 35% from fundamental to DUV.
