With this paper, The brand new lapping slurry and polishing slurry are introduced. As well as the deliquescence diploma of CLBO is fallen to most affordable. A whole new Doing the job engineering can be adopted. Just after tough sprucing, the concentration of ultra-precision sprucing slurry is elevated effectively. So does the ultra-precision polishing velocity, as well as wiping velocity is quicker as opposed to deliquescence speed. The CLBO crystal area roughness can obtain 1nm and preserve the surface area excellent perfectly. Access via your establishment

We summarized the current enhancement standing of the significant-electrical power DUV laser both for the wavelength of FHG from the one-μm laser and at 193 nm. The recent progress from the solid-condition/fiber laser, as well as the nonlinear optical crystals, prompts not merely the standard electrical power but will also the beam high quality (coherence) on the DUV lasers to an unparalleled stage.
The common energy in the NIR laser nonetheless has the probable to be improved to tens of watts for instance 70 W [26] When the double-move configuration can be utilized for that Yb:YAG SCF amplifier phase. Hence, In the event the conversion performance of 31% from NIR to DUV might be even now preserved at this increased electric power ailment, the common output power of the DUV laser at 258 nm might be greater than 20 W, which would be considered a outstanding energy amount for that DUV laser and cause the unanticipated DUV laser machining final results. Also, for prime-electrical power DUV laser, the UV harm of your nonlinear crystal, including the Home windows for CLBO crystal plus the mirrors, is an additional important parameter for lasting and stable Procedure.

Moreover, combining the stable-condition laser with other nonlinear method including stimulated Raman scattering, NIR lasers could possibly be achieved at new wavelengths with significant electrical power and high beam quality, which was analyzed via the proof-of-basic principle experiment. This Raman laser scheme gives a whole new path to the substantial-electric power DUV laser, Primarily at the wavelength of 193 nm.

The development with the 193-nm laser was demonstrated by phases of SFG. In order to scale the DUV laser electricity effectively, a whole new thought from the 193-nm DUV laser era is introduced according to the diamond Raman laser.
