According to the evidence-of-principle experiment, the conversion effectiveness of 23% implied the opportunity of attaining substantial-electricity at the 2nd Stokes wavelength of your Raman laser. In the event the pump laser of 1078 nm may very well be attained at the average ability of 50 W, the output electricity of its 2nd Stokes wavelength at 1512 nm can be much more than ten W. The design from the Raman laser cavity ought to be optimized in order to steer clear of the hurt in 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。

Each the 1040 nm and 1078 nm laser come from one twin-wavelength Yb-doped fiber laser. Each individual laser is amplified by phases of fiber amplifier and Yb-doped components amplifier, respectively.
On read more another side, the facility scaling with the NIR laser is an additional element to increase the ordinary electricity on the 193-nm DUV laser. Because of the insufficient the higher-power amplification Option on the NIR laser (as an example at 1553 nm), nonlinear frequency procedures including optical parameter oscillation (OPO) could be applied to build a wavelength converter by shifting the wavelength from 1 μm to the specified wavelength as well as acquiring relative better energy [21]. A short while ago, a diamond Raman laser showed its capacity in accomplishing a high energy plus a significant conversion performance for the 1st Stokes of your one-μm laser [22,23], which means the chance to generally be utilized within the 193-nm DUV laser era thanks to its high Raman acquire and large frequency change.

Its UV absorption edge reaches a hundred and eighty nm. The productive nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about twice as significant as that of KDP. CLBO crystals might be developed in the stoichiometric melt with decreased viscosity.
