During this paper, The brand new lapping slurry and polishing slurry are introduced. As well as deliquescence degree of CLBO is fallen to least expensive. A fresh working know-how is additionally adopted. Right after rough polishing, the concentration of extremely-precision sprucing slurry is amplified thoroughly. So does the extremely-precision sprucing velocity, plus the wiping pace is faster compared to deliquescence velocity. The CLBO crystal surface roughness can attain 1nm and preserve the area quality well. Entry by your institution

In accordance with the evidence-of-theory experiment, the conversion performance of 23% implied the possibility of reaching higher-electrical power at the second Stokes wavelength of your Raman laser. If your pump laser of 1078 nm could possibly be obtained at the standard electricity of fifty W, the output electric power of its 2nd Stokes wavelength at 1512 nm can be in excess of 10 W. The design of your Raman laser cavity needs to be optimized in order to steer clear of the destruction of your M1 and diamond surface area.
The average power of your NIR laser nevertheless has the possible being improved to tens of watts such as 70 W [26] When the double-pass configuration could be used to the Yb:YAG SCF amplifier phase. For this reason, In case the conversion efficiency of 31% from NIR to DUV could possibly be continue to taken care of at this better power problem, the standard output electricity of your DUV laser at 258 nm could possibly be in excess of twenty W, which might certainly be a extraordinary ability amount for your DUV laser and cause the unanticipated DUV laser machining success. Additionally, for top-power DUV laser, the UV injury on the nonlinear crystal, including the Home windows for CLBO crystal plus the mirrors, is an additional significant parameter for long run and stable operation.
Conversely, the beam good quality of the increased energy DUV laser would come to be worse resulting from more really serious thermal and nonlinear consequences. Consequently, the frequency conversion processes really should be carefully made to mitigate the aforementioned results. Consequently, a superior-power DUV laser on the FHG of 1 μm with an excellent beam high-quality could possibly be attained and can be valuable for getting the shorter here wavelength DUV lasers such as 193 nm by SFG.
Each the 1040 nm and 1078 nm laser come from a single dual-wavelength Yb-doped fiber laser. Each and every laser is amplified by stages of fiber amplifier and Yb-doped products amplifier, respectively.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the most effective non-linear crystal which generates ultraviolet harmonics of your Nd:YAG elementary laser wavelength. As a way to enhance the problems threshold, small CLBO surface area roughness, by extremely-precision machining, is required. As the CLBO crystal has easy hydroscopic response and micro scratches in machining, extremely-exact machining of the CLBO crystal is often a tough technological challenge.
