All-strong-condition ultraviolet lasers are already broadly Utilized in the fields of mechanical flaw detection, lithography, micromachining and medicine for some great benefits of small quantity, long life, substantial effectiveness, fantastic beam high-quality, wide tuning and narrow spectral line, etcetera. Making use of large energy in the vicinity of-infrared coherent light resource as the basic frequency resource based upon nonlinear tuning engineering, making ultraviolet coherent radiation by multistage frequency conversion is regarded as a very important strategy to build the ultraviolet coherent gentle 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。
Alternatively, the beam good quality of this bigger ability DUV laser would develop into worse resulting from much more really serious thermal and nonlinear effects. For this reason, the frequency conversion processes needs to be diligently designed to mitigate the aforementioned effects. Hence, a significant-ability DUV laser at the FHG of 1 μm with a good beam high quality could possibly be acquired and will be beneficial for getting the shorter wavelength DUV lasers which include 193 nm by SFG.
Mainly because of the thermal lens influence while in the strong-point out lasers, If your heating management is inadequate, It's not at all easy to acquire the reliable-state laser by using a higher electricity and a significant beam top quality at the same time. Just lately, with the event of the thin disk laser and solitary-crystal fiber (SCF) laser, a high-electric power laser at the elemental wavelength (1 μm) had been understood with a good beam top quality In spite of a TEM00 manner beam [four,24], which might be superior candidates for the fundamental from the DUV laser generation. Yet another applicant for the basic could be the superior-power fiber laser which might be realized by coherent beam blend with M2 worth less than 1.

Moreover, combining the reliable-point out laser get more info with other nonlinear approach such as stimulated Raman scattering, NIR lasers may be accomplished at new wavelengths with substantial power and large beam high-quality, which was analyzed from the proof-of-principle experiment. This Raman laser scheme supplies a different path to the superior-power DUV laser, Particularly in the wavelength of 193 nm.
The beam profile demonstrated in Figure 7b demonstrated a fantastic beam quality as one of many merits of Raman laser, which would be useful to crank out a 193-nm DUV laser with a high quality beam.
The conversion efficiency from elementary NIR to DUV is from 5% to 36% in accordance with the described leads to Desk 1. Increasing the conversion effectiveness will reduce the load on the look and setup of the basic laser amplifier as well as the electrical power intake. A very good beam good quality of the elemental laser may also add to the escalating with the conversion performance as well as the appropriate electricity depth with the NIR and environmentally friendly laser in 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 around fifty%, respectively [twelve], which corresponds on the conversion effectiveness of 35% from basic to DUV.
The development of your 193-nm laser was demonstrated by levels of SFG. In an effort to scale the DUV laser energy correctly, a fresh thought on the 193-nm DUV laser technology is presented determined by the diamond Raman laser.
