All-strong-condition ultraviolet lasers are widely used in the fields of mechanical flaw detection, lithography, micromachining and medicine for some great benefits of small quantity, very long everyday living, significant effectiveness, excellent beam top quality, wide tuning and slender spectral line, and so forth. Using high power near-infrared coherent light-weight supply as the fundamental frequency resource dependant on nonlinear tuning technological know-how, making ultraviolet coherent radiation by multistage frequency conversion is regarded as a very important approach to develop the ultraviolet coherent mild 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。

LBO can also be a wonderful nonlinear crystal which is usually placed on the SHG in the NIR to your green. The DUV laser is frequently understood by two levels of SFG within the LBO crystals due to the fact there isn't any stage-matching angle for LBO to convert the green laser at 515 nm or 532 nm on the DUV immediately by SHG [16]. Just lately, the NSBBF crystal has also demonstrated its prospective to get a large conversion performance from 532 nm to 266 nm. The stroll-off angle and deff on the NSBBF are Virtually much like those of CLBO [seventeen].

In addition, combining the reliable-point out laser with other nonlinear method which include stimulated Raman scattering, NIR lasers may be achieved at new wavelengths with substantial ability and large beam excellent, which was analyzed from the proof-of-theory experiment. This Raman laser plan presents a fresh path to the significant-power DUV laser, especially in the wavelength of 193 nm.
