The 2-Minute Rule for CLBO Crystal
Blog Article
On this paper, The brand new lapping slurry and sprucing slurry are launched. And the deliquescence degree of CLBO is fallen to cheapest. A completely new Operating engineering is likewise adopted. Just after tough sharpening, the concentration of extremely-precision polishing slurry is enhanced adequately. So does the extremely-precision polishing speed, along with the wiping pace is quicker compared to the deliquescence speed. The CLBO crystal surface roughness can achieve 1nm and keep the area high-quality perfectly. Entry by way of your establishment

In accordance with the evidence-of-basic principle experiment, the conversion efficiency of 23% implied the potential of accomplishing high-ability at the 2nd Stokes wavelength on the Raman laser. Should the pump laser of 1078 nm could be obtained at the typical energy of 50 W, the output power of its 2nd Stokes wavelength at 1512 nm could be a lot more than 10 W. The design in the Raman laser cavity should be optimized in order to stay away from the hurt of the M1 and diamond area.
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 high-quality of this increased ability DUV laser would grow to be even worse because of far more major thermal and nonlinear effects. That's why, the frequency conversion processes really should be carefully made to mitigate the aforementioned results. As a result, a high-electric power DUV laser within the FHG of one μm with an excellent beam high-quality can be attained and will be effective for acquiring the shorter wavelength DUV lasers such as 193 nm by SFG.

The pulse length of the second Stokes gentle was shortened to five ns as proven in Determine 7a, just one-shot image from the oscilloscope, and that is a common phenomenon in Raman laser [forty four] while the heart beat length of your pump laser was 10 ns.

The beam profile proven in Figure 7b demonstrated a fantastic beam high-quality as among the merits of Raman laser, which might be effective to generate a 193-nm DUV laser with a high quality beam.

The development of your 193-nm laser was demonstrated by phases of SFG. In order to scale the DUV laser electricity correctly, a fresh strategy of the 193-nm DUV laser era is offered dependant on more info the diamond Raman laser.
