All-solid-point out ultraviolet lasers have been greatly Employed in the fields of mechanical flaw detection, lithography, micromachining and drugs for the benefits of modest quantity, extensive everyday living, superior effectiveness, very good beam quality, vast tuning and narrow spectral line, and so on. Employing large electricity around-infrared coherent mild supply as the elemental frequency supply according to nonlinear tuning engineering, building ultraviolet coherent radiation by multistage frequency conversion is regarded as a significant approach to establish the ultraviolet coherent light supply.
As compared to BBO it characteristics bigger spectral and temperature acceptance, greater angle tolerance, along with a more compact wander-off angle. from 3289 $ shipping and delivery
According to the proof-of-basic principle experiment, the conversion effectiveness of 23% implied the opportunity of attaining superior-energy at the next Stokes wavelength of your Raman laser. When the pump laser of 1078 nm may be acquired at the average electric power of fifty W, the output electric power of its 2nd Stokes wavelength at 1512 nm can be more than ten W. The design in the Raman laser cavity needs to be optimized as a way to avoid the damage in the M1 and diamond surface.
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。

Furthermore, combining the stable-state laser with other nonlinear procedure for instance read more stimulated Raman scattering, NIR lasers may be achieved at new wavelengths with higher energy and substantial beam high quality, which was analyzed because of the evidence-of-basic principle experiment. This Raman laser plan provides a completely new path to the higher-power DUV laser, Specially on the wavelength of 193 nm.
The beam profile demonstrated in Figure 7b shown an excellent beam top quality as among the merits of Raman laser, which would be beneficial to make a 193-nm DUV laser with a top quality beam.
Its UV absorption edge reaches a hundred and eighty nm. The efficient nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as huge as that of KDP. CLBO crystals may be grown from the stoichiometric melt with lessen viscosity.
