In this paper, the new lapping slurry and polishing slurry are introduced. Along with the deliquescence diploma of CLBO is fallen to least expensive. A fresh Doing the job technological innovation is additionally adopted. Immediately after tough polishing, the concentration of extremely-precision sprucing slurry is amplified properly. So does the extremely-precision sharpening speed, and also the wiping velocity is faster compared to deliquescence speed. The CLBO crystal floor roughness can attain 1nm and maintain the floor top quality effectively. Access by means of your establishment

Based on the evidence-of-theory experiment, the conversion efficiency of 23% implied the potential for reaching substantial-electricity at the next Stokes wavelength from the Raman laser. Should the pump laser of 1078 nm could possibly be obtained at the common ability of fifty W, the output electricity of its 2nd Stokes wavelength at 1512 nm may be a lot more than 10 W. The look in the Raman laser cavity must be optimized so as to avoid the harm with the M1 and diamond floor.
The normal energy in the NIR laser even now has the potential to get enhanced to tens of watts for example 70 W [26] if the double-move configuration could possibly be utilized for the Yb:YAG SCF amplifier stage. Consequently, In case the conversion performance of 31% from NIR to DUV may very well be nonetheless preserved at this larger electrical power problem, the average output ability in the DUV laser at 258 nm can be much more than twenty W, which might be a outstanding electricity degree for your DUV laser and bring about the unanticipated DUV laser machining results. What's more, for top-energy DUV laser, the UV destruction with the nonlinear crystal, including the Home windows for CLBO crystal plus the mirrors, is yet another important parameter for lasting and secure Procedure.

Both the 1040 nm and 1078 nm laser originate from one twin-wavelength Yb-doped fiber laser. Every laser is amplified by stages of fiber amplifier and Yb-doped materials amplifier, respectively.

Tunable ultraviolet laser source dependant on sound-point out dye laser technological innovation and CsLiB6O10 harmonic technology
The conversion performance from essential NIR to DUV is from 5% to 36% based on the described brings about Desk 1. Escalating the conversion effectiveness will lessen the stress on the look and set up of the fundamental laser amplifier in addition to the electrical electric power use. A very good beam high quality of the fundamental laser will even lead on the rising with the conversion performance and the right ability depth with the NIR and environmentally friendly laser during the SHG and FHG system, respectively. The best conversion efficiencies from NIR to inexperienced and inexperienced to DUV laser by utilization of CLBO crystal are 70% and close to 50%, respectively [12], which corresponds into the conversion performance of 35% from elementary to DUV.
The event on the 193-nm laser was demonstrated by levels of SFG. In an effort to scale the DUV laser energy correctly, a whole new idea with the 193-nm DUV laser era is introduced depending on the diamond Raman laser.
