With this paper, The brand new lapping slurry and polishing slurry are introduced. Plus the deliquescence degree of CLBO is fallen to most affordable. A completely new Functioning technological know-how is also adopted. After rough sharpening, the focus of ultra-precision sprucing slurry is improved adequately. So does the extremely-precision sprucing velocity, as well as wiping velocity is quicker in comparison to the deliquescence pace. The CLBO crystal surface roughness can attain 1nm and maintain the area high-quality well. Obtain by way of your institution

In accordance with the proof-of-theory experiment, the conversion efficiency of 23% implied the potential of accomplishing superior-ability at the second Stokes wavelength on the Raman laser. Should the pump laser of 1078 nm could be obtained at the typical electrical power of 50 W, the output energy of its 2nd Stokes wavelength at 1512 nm may be more than ten W. The design from the Raman laser cavity ought to be optimized as a way to avoid the injury from the M1 and diamond surface.
The key dilemma of ultraviolet coherent light-weight resource predominantly concentrates on the event of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is amongst the problems for frequency transformation, so The expansion, sizing, destruction resistance, conversion performance and allowable parameter number of nonlinear optical crystal are expected more and more.
Conversely, the beam high quality of the higher power DUV laser would come to be even worse due to a lot more critical thermal and nonlinear outcomes. Therefore, the frequency conversion processes needs to be very carefully intended to mitigate the aforementioned results. Hence, a higher-electricity DUV laser on the FHG of 1 μm with a very good beam excellent could more info possibly be obtained and will be helpful for getting the shorter wavelength DUV lasers including 193 nm by SFG.
Both of those the 1040 nm and 1078 nm laser originate from one particular dual-wavelength Yb-doped fiber laser. Each individual laser is amplified by levels of fiber amplifier and Yb-doped elements amplifier, respectively.

Furthermore, combining the stable-point out laser with other nonlinear procedure for example stimulated Raman scattering, NIR lasers could be reached at new wavelengths with superior energy and substantial beam excellent, which was analyzed by the proof-of-principle experiment. This Raman laser plan provides a brand new route to the superior-ability DUV laser, Particularly on the wavelength of 193 nm.

Its UV absorption edge reaches a hundred and eighty nm. The powerful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as big as that of KDP. CLBO crystals is usually grown from the stoichiometric melt with reduce viscosity.
