In accordance with the evidence-of-principle experiment, the conversion effectiveness of 23% implied the potential for achieving higher-electrical power at the 2nd Stokes wavelength on the Raman laser. Should the pump laser of 1078 nm might be acquired at the common electricity of fifty W, the output electric power of its 2nd Stokes wavelength at 1512 nm can be more than 10 W. The look of your Raman laser cavity need to be optimized so as to steer clear of the destruction on the M1 and diamond floor.
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。

Both the 1040 nm and 1078 nm laser originate from just one dual-wavelength Yb-doped fiber laser. Each and every laser is amplified by stages of fiber amplifier and Yb-doped products amplifier, respectively.
On one other facet, the power scaling of the NIR laser is another aspect to enhance the ordinary ability with the 193-nm DUV laser. Due to insufficient the large-electric power amplification Remedy of the NIR laser (for example at 1553 nm), nonlinear frequency processes including optical parameter oscillation (OPO) may very well be placed on produce a wavelength converter by shifting the wavelength from 1 μm to the desired wavelength as well as obtaining relative larger ability [21]. Just lately, a diamond Raman laser showed its capacity in accomplishing a substantial ability and more info also a superior conversion efficiency in the 1st Stokes of your one-μm laser [22,23], which means the chance being utilized while in the 193-nm DUV laser generation as a result of its higher Raman gain and enormous frequency shift.

The pulse period of the second Stokes mild was shortened to five ns as demonstrated in Determine 7a, one-shot picture within the oscilloscope, that's a standard phenomenon in Raman laser [44] though the pulse length of the pump laser was 10 ns.

Its UV absorption edge reaches 180 nm. The helpful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as huge as that of KDP. CLBO crystals can be developed from your stoichiometric soften with decrease viscosity.
The development on the 193-nm laser was shown by stages of SFG. So as to scale the DUV laser energy proficiently, a brand new principle of your 193-nm DUV laser generation is offered according to the diamond Raman laser.
