In this paper, The brand new lapping slurry and sharpening slurry are released. And also the deliquescence diploma of CLBO is fallen to least expensive. A brand new Functioning know-how is additionally adopted. Just after tough sprucing, the concentration of extremely-precision sprucing slurry is increased correctly. So does the extremely-precision sharpening velocity, plus the wiping pace is faster compared to deliquescence speed. The CLBO crystal floor roughness can realize 1nm and preserve the area top quality very well. Access by way of your institution

We summarized the current progress standing of the high-ability DUV laser both within the wavelength of FHG in the one-μm laser and at 193 nm. The latest enhancement in the good-state/fiber laser, and also the nonlinear optical crystals, prompts not merely the average ability but additionally the beam excellent (coherence) of the DUV lasers to an unprecedented level.
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。

LBO can also be a fantastic nonlinear crystal which is always applied to the SHG through the NIR into the green. The DUV laser is normally recognized by two phases of SFG from the LBO crystals since there's no period-matching angle for LBO to transform the inexperienced laser at 515 nm or 532 nm on the DUV specifically by SHG [sixteen]. Not long ago, the NSBBF crystal has also shown its potential to acquire a superior conversion effectiveness from 532 nm to 266 nm. The walk-off angle and deff from the NSBBF are almost much like those of CLBO [seventeen].

Its UV absorption edge reaches 180 nm. The helpful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as large as that of KDP. CLBO crystals might be grown through the stoichiometric soften with lessen viscosity.
