According to the evidence-of-principle experiment, the conversion effectiveness of 23% implied the opportunity of attaining significant-energy at the next Stokes wavelength of your Raman laser. When the pump laser of 1078 nm could be attained at the standard ability of 50 W, the output energy of its 2nd Stokes wavelength at 1512 nm might be greater than ten W. The look on the Raman laser cavity must be optimized in an effort to stay away from the destruction 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。

LBO can be a wonderful nonlinear crystal which is always applied to the SHG with the NIR to the green. The DUV laser is often recognized by two phases of SFG from the LBO crystals because there isn't a period-matching angle for LBO to transform the inexperienced laser at 515 nm or 532 nm towards the DUV immediately by SHG [16]. A short while ago, the NSBBF crystal has also shown its possible to obtain a higher conversion efficiency from 532 nm to 266 nm. The wander-off angle and deff of your NSBBF are almost similar to those of CLBO [seventeen].
On one other facet, the ability scaling of the NIR laser is yet another part to improve the regular electric power with the 193-nm DUV laser. Due to insufficient the higher-ability amplification Option in the NIR laser (one example is at 1553 nm), nonlinear frequency processes for example optical parameter oscillation (OPO) could be applied to produce a wavelength converter by shifting the wavelength from 1 μm to the desired wavelength together with acquiring relative greater electricity [21]. Recently, a diamond Raman laser showed its capacity in accomplishing a superior power along with a large conversion effectiveness for the CLBO Crystal 1st Stokes on the 1-μm laser [22,23], which suggests the likelihood for being used in the 193-nm DUV laser generation due to its higher Raman obtain and large frequency shift.

The heart beat period of the second Stokes light-weight was shortened to 5 ns as revealed in Determine 7a, a single-shot photograph from your oscilloscope, that is a standard phenomenon in Raman laser [44] when the pulse period from the pump laser was ten ns.
Furthermore, combining the good-state laser with other nonlinear system including stimulated Raman scattering, NIR lasers can be achieved at new wavelengths with substantial ability and high beam high quality, which was examined via the evidence-of-basic principle experiment. This Raman laser plan presents a new route to the high-energy DUV laser, Specifically on the wavelength of 193 nm.
