All-reliable-state ultraviolet lasers have already been extensively Utilized in the fields of mechanical flaw detection, lithography, micromachining and drugs for the benefits of little quantity, extended life, superior performance, fantastic beam quality, large tuning and narrow spectral line, and so on. Making use of substantial ability close to-infrared coherent light-weight supply as the fundamental frequency source depending on nonlinear tuning technological know-how, building ultraviolet coherent radiation by multistage frequency conversion is regarded as a vital technique to acquire the ultraviolet coherent gentle resource.
In comparison with BBO it capabilities much larger spectral and temperature acceptance, better angle tolerance, along with a smaller sized walk-off angle. from 3289 $ delivery
According to the proof-of-basic principle experiment, the conversion efficiency of 23% implied the potential for obtaining superior-electric power at the next Stokes wavelength of the Raman laser. When the pump laser of 1078 nm could possibly be received at the common ability of 50 W, the output energy of its 2nd Stokes wavelength at 1512 nm may very well be a lot more than 10 W. The design of your Raman laser cavity must be optimized as a way to avoid the problems on 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。

In addition, combining the sound-condition laser with other nonlinear approach which include stimulated Raman scattering, NIR lasers could be achieved at new wavelengths with large electricity and higher beam high-quality, which was tested because of the proof-of-basic principle experiment. This Raman laser scheme gives a new route to the significant-energy DUV laser, In particular on the wavelength of 193 nm.
Tunable ultraviolet laser source determined by sound-point out dye laser know-how and CsLiB6O10 harmonic generation
The conversion efficiency from essential NIR to DUV is from 5% to 36% based on the described brings about Desk one. Increasing the conversion efficiency will reduce the load on the design and setup of the fundamental laser amplifier in addition to the electrical electricity intake. A fantastic beam high-quality of the elemental laser will also add towards the rising on the conversion effectiveness and also the suitable electricity intensity from the NIR and green laser inside the SHG and FHG procedure, respectively. The highest conversion efficiencies from NIR to green and green to DUV laser by use of CLBO crystal are 70% and about fifty%, respectively [twelve], which corresponds towards the conversion effectiveness of 35% from elementary to DUV.
