All-reliable-point out ultraviolet lasers have been widely used in the fields of mechanical flaw detection, lithography, micromachining and drugs for some great benefits of compact quantity, very long everyday living, superior efficiency, good beam quality, large tuning and slim spectral line, etc. Employing superior electric power in close proximity to-infrared coherent mild resource as the basic frequency resource based upon nonlinear tuning know-how, making ultraviolet coherent radiation by multistage frequency conversion is considered a very important approach to develop the ultraviolet coherent light-weight source.

According to the proof-of-theory experiment, the conversion effectiveness of 23% implied the opportunity of reaching large-electric power at the next Stokes wavelength with the Raman laser. Should the pump laser of 1078 nm can be obtained at the average energy of 50 W, the output power of its 2nd Stokes wavelength at 1512 nm could be more than ten W. The design from the Raman laser cavity really should be optimized as a way to stay away from the injury from 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。
Then again, the beam excellent of the bigger power DUV laser would turn out to be worse due to far more major thermal and nonlinear consequences. As a result, the frequency conversion processes need to be carefully created to mitigate the aforementioned effects. Therefore, a large-electricity DUV laser for the FHG of one μm with a good beam top quality could possibly be acquired and will be beneficial for getting the shorter wavelength DUV lasers which include 193 nm by SFG.
As a result of thermal lens impact within the solid-point out lasers, In the event the heating management is inadequate, It's not simple to acquire the good-condition laser with a substantial energy in addition to a substantial beam quality concurrently. Recently, with the development of The skinny disk laser and one-crystal fiber (SCF) laser, a higher-electricity laser at the elemental wavelength (1 μm) were understood with a superb beam quality Despite a TEM00 method beam [4,24], which would be fantastic candidates for the elemental of the DUV laser generation. An additional candidate for the fundamental may be the significant-electrical power fiber laser which could be achieved by coherent beam mix with M2 benefit fewer than one.

The development in the 193-nm laser was shown by stages of SFG. So that you can scale the DUV laser electrical power correctly, a whole new thought in the 193-nm DUV laser technology is introduced depending on the diamond Raman laser.
