The 2-Minute Rule for CLBO Crystal
Blog Article
During this paper, the new lapping slurry and sharpening slurry are released. As well as the deliquescence degree of CLBO is fallen to least expensive. A different Functioning technologies is also adopted. Immediately after rough sharpening, the focus of extremely-precision sprucing slurry is increased properly. So does the ultra-precision sharpening pace, and also the wiping speed is faster compared to the deliquescence pace. The CLBO crystal floor roughness can achieve 1nm and hold the surface high-quality nicely. Access by way of your institution

Based on the proof-of-basic principle experiment, the conversion efficiency of 23% implied the possibility of acquiring higher-electric power at the next Stokes wavelength in the Raman laser. If the pump laser of 1078 nm can be acquired at the average power of 50 W, the output ability of its 2nd Stokes wavelength at 1512 nm might be in excess of ten W. The look from the Raman laser cavity need to be optimized as a way to steer clear of the destruction of the M1 and diamond surface.
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。
Alternatively, the beam top quality of the increased electrical power DUV laser would turn out to be even worse as a result of extra significant thermal and nonlinear outcomes. Therefore, the frequency conversion procedures must be meticulously created to mitigate the aforementioned results. Consequently, a significant-power DUV laser in the FHG of 1 μm with a good beam quality could be acquired and may be advantageous for acquiring the shorter wavelength DUV lasers for example 193 nm by SFG.
Both of those the 1040 nm and 1078 nm laser originate from a person dual-wavelength Yb-doped fiber laser. Just about every laser is amplified by phases of fiber amplifier and Yb-doped resources amplifier, respectively.

The conversion effectiveness from elementary NIR to DUV is from five% to 36% according to the reported leads to Table 1. Escalating the conversion effectiveness will decrease the stress on the look and set up of the basic laser amplifier plus the electric ability consumption. An excellent beam high-quality of the fundamental laser will even contribute to your rising in the conversion efficiency and also the suitable electric power depth on the NIR and environmentally friendly laser in the SHG and FHG approach, respectively. The very best conversion efficiencies from NIR to environmentally friendly and inexperienced to DUV laser by use of CLBO crystal are 70% and about 50%, respectively [twelve], which corresponds to the conversion performance of 35% from fundamental to DUV.
The event in the 193-nm laser was shown by levels of SFG. As a way to scale the DUV laser electrical power efficiently, a more info completely new concept of your 193-nm DUV laser technology is introduced depending on the diamond Raman laser.
