All-good-point out ultraviolet lasers have been extensively used in the fields of mechanical flaw detection, lithography, micromachining and medicine for the advantages of little volume, prolonged existence, substantial efficiency, good beam good quality, extensive tuning and slender spectral line, and so forth. Using substantial electricity in the vicinity of-infrared coherent light supply as the basic frequency supply according to nonlinear tuning technological innovation, generating ultraviolet coherent radiation by multistage frequency conversion is viewed as a crucial technique to create the ultraviolet coherent light supply.

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。
Then again, the beam top quality of the larger energy DUV laser would come to be worse due to much more major thermal and nonlinear results. As a result, the frequency conversion processes must be diligently created to mitigate the aforementioned outcomes. So, a high-energy DUV laser on the FHG of 1 μm with a superb beam high-quality could be obtained and may be effective for acquiring the shorter wavelength DUV lasers for example 193 nm by SFG.
LBO is additionally an excellent nonlinear crystal which is always applied to the SHG within the NIR on the green. The DUV laser is often recognized by two levels of SFG within the LBO crystals due to the fact there's no period-matching angle for LBO to transform the environmentally friendly laser at 515 nm or 532 nm towards the DUV straight by SHG [16]. Not long click here ago, the NSBBF crystal has also revealed its prospective to obtain a higher conversion efficiency from 532 nm to 266 nm. The walk-off angle and deff of the NSBBF are almost just like All those of CLBO [seventeen].

Its UV absorption edge reaches a hundred and eighty nm. The helpful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as massive as that of KDP. CLBO crystals could be grown from the stoichiometric melt with lessen viscosity.
