As compared to BBO it characteristics greater spectral and temperature acceptance, better angle tolerance, and also a smaller sized stroll-off angle. from 3289 $ supply
According to the evidence-of-principle experiment, the conversion efficiency of 23% implied the potential for achieving higher-electricity at the next Stokes wavelength of the Raman laser. In the event the pump laser of 1078 nm may very well be attained at the typical power of 50 W, the output electrical power of its 2nd Stokes wavelength at 1512 nm may be a lot more than 10 W. The look with the Raman laser cavity really should be optimized as a way to stay away from the injury of the M1 and diamond 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。

Both of those the 1040 nm and 1078 nm laser originate from one dual-wavelength Yb-doped fiber laser. Each and every laser is amplified by stages of fiber amplifier and Yb-doped products amplifier, respectively.

Additionally, combining the solid-state laser with other nonlinear procedure for instance stimulated Raman scattering, NIR lasers may be achieved at new wavelengths with substantial electricity and superior beam top quality, which was examined with the proof-of-principle experiment. This Raman laser plan supplies a new route to the substantial-electricity DUV laser, Primarily on the wavelength of 193 nm.

The conversion effectiveness from essential NIR to DUV is from 5% to 36% in accordance with the noted brings about Table one. Increasing the conversion effectiveness will lessen the burden on the design and set up of the elemental laser amplifier plus the electric powered energy intake. A very good beam top quality of the basic laser can even lead into the growing on the conversion performance as well as the suitable power intensity in the NIR and inexperienced laser during the SHG and FHG process, respectively. The highest conversion efficiencies from NIR to green and green to DUV laser by usage of CLBO crystal are 70% and all-around fifty%, respectively [12], which corresponds for the conversion efficiency of 35% from fundamental to DUV.
