All-reliable-point out ultraviolet lasers happen to be widely used in the fields of mechanical flaw detection, lithography, micromachining and medicine for the benefits of modest quantity, lengthy existence, higher efficiency, superior beam good quality, vast tuning and narrow spectral line, etcetera. Using higher electricity close to-infrared coherent light resource as the basic frequency resource according to nonlinear tuning technologies, generating ultraviolet coherent radiation by multistage frequency conversion is considered to be a vital approach to develop the ultraviolet coherent mild supply.
As compared to BBO it attributes greater spectral and temperature acceptance, better angle tolerance, plus a smaller stroll-off angle. from 3289 $ supply
Based on the proof-of-basic principle experiment, the conversion effectiveness of 23% implied the potential for achieving higher-electricity at the next Stokes wavelength of your Raman laser. If your pump laser of 1078 nm could possibly be attained at the normal electrical power of 50 W, the output ability of its 2nd Stokes wavelength at 1512 nm may be much more than ten W. The design with the Raman laser cavity should be optimized so that you can avoid the problems of the M1 and diamond surface 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。

LBO can also be a superb nonlinear crystal which is usually placed on the SHG within the NIR into the environmentally friendly. The DUV laser is usually understood by two phases of SFG while in the LBO crystals due to the fact there isn't a stage-matching angle for LBO to convert the environmentally friendly laser at 515 nm or 532 nm towards the DUV straight by SHG [16]. Lately, the NSBBF crystal has also shown its opportunity to get a large conversion efficiency from 532 nm to 266 nm. The wander-off angle and deff in the NSBBF are Just about much like These of CLBO [seventeen].

The beam profile revealed in Figure 7b demonstrated a fantastic beam quality as one of several deserves of Raman laser, which might be valuable to create a 193-nm DUV laser with a high quality beam.
Its UV absorption edge reaches one hundred eighty 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 can be grown in the stoichiometric melt with lessen viscosity.
