On this paper, The brand new lapping slurry and sprucing slurry are introduced. As well as the deliquescence diploma of CLBO is fallen to least expensive. A different Functioning know-how is additionally adopted. Immediately after tough sprucing, the focus of extremely-precision sharpening slurry is greater thoroughly. So does the extremely-precision sprucing velocity, and also the wiping pace is faster compared to the deliquescence velocity. The CLBO crystal surface roughness can attain 1nm and preserve the surface quality well. Obtain by means of your institution

The common energy of your NIR laser however has the likely to become enhanced to tens of watts including 70 W [26] if the double-move configuration could be used for the Yb:YAG SCF amplifier phase. Therefore, If your conversion efficiency of 31% from NIR to DUV may very well be nonetheless preserved at this higher power situation, the typical output power from the DUV laser at 258 nm can be much more than twenty W, which might certainly be a impressive power stage with the DUV laser and lead to the unanticipated DUV laser machining success. Additionally, for prime-energy DUV laser, the UV damage in the nonlinear crystal, including the Home windows for CLBO crystal as well as the mirrors, is another crucial parameter for lasting and stable Procedure.

On the opposite aspect, the ability scaling in the NIR laser is yet another factor to increase the normal ability of the 193-nm DUV laser. Due to the deficiency of the higher-electric power amplification Remedy with the NIR laser (for instance at 1553 nm), nonlinear frequency processes for example optical parameter oscillation (OPO) could be applied to build a wavelength converter by shifting the wavelength from 1 μm to the desired wavelength along with acquiring relative higher electrical power [21]. Not long ago, a diamond Raman laser confirmed its skill in accomplishing a superior ability and a large conversion efficiency in the 1st Stokes with the 1-μm laser [22,23], which implies the possibility for being applied within the 193-nm DUV laser technology as a consequence of its substantial Raman obtain and enormous frequency shift.

The heartbeat period of the second Stokes mild was shortened to five ns as revealed in Figure 7a, one-shot photograph from your oscilloscope, which happens to be a common phenomenon in Raman laser [44] even though the pulse length of your pump laser was ten ns.

Its UV absorption edge reaches 180 nm. The powerful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about twice as big as that of KDP. CLBO crystals is usually developed in the stoichiometric soften with decrease viscosity.
