On this paper, the new lapping slurry and sharpening slurry are launched. As well as the deliquescence degree of CLBO is fallen to most affordable. A fresh Performing technology can be adopted. Following rough sharpening, the concentration of ultra-precision polishing slurry is increased effectively. So does the ultra-precision polishing speed, as well as the wiping speed is quicker compared to the deliquescence velocity. The CLBO crystal floor roughness can obtain 1nm and retain the surface quality perfectly. Entry via your establishment

According to the evidence-of-basic principle experiment, the conversion efficiency of 23% implied the potential of obtaining high-ability at the next Stokes wavelength from the Raman laser. Should the pump laser of 1078 nm may very well be acquired at the average electric power of 50 W, the output power of its 2nd Stokes wavelength at 1512 nm may be greater than 10 W. The design with the Raman laser cavity should be optimized to be able to stay away from the problems with the M1 and diamond surface.
The average electric power from the NIR laser nevertheless has the probable to be improved to tens of watts such as 70 W [26] If your double-move configuration can be used with the Yb:YAG SCF amplifier phase. Consequently, When the conversion efficiency of 31% from NIR to DUV can be even now managed at this greater power affliction, the standard output power with the DUV laser at 258 nm could possibly be greater than 20 W, which might certainly be a amazing electrical power amount to the DUV laser and lead to the unanticipated DUV laser machining final results. Moreover, for prime-electricity DUV laser, the UV harm of your nonlinear crystal, such as the Home windows for CLBO crystal along with the mirrors, is an additional important parameter for long term and stable Procedure.
Conversely, the beam high quality of the increased power DUV laser would grow to be worse resulting from much more major thermal and nonlinear effects. Therefore, the frequency conversion processes need to be carefully created to mitigate the aforementioned results. Thus, a high-energy DUV laser at the FHG of 1 μm with a great beam more info quality can be obtained and can be advantageous for getting the shorter wavelength DUV lasers such as 193 nm by SFG.
As a result of thermal lens outcome inside the strong-point out lasers, In case the heating management is inadequate, It's not quick to obtain the solid-state laser having a high energy in addition to a high beam top quality at the same time. Just lately, with the development of the thin disk laser and one-crystal fiber (SCF) laser, a superior-ability laser at the elemental wavelength (1 μm) had been understood with a superb beam top quality Despite a TEM00 mode beam [4,24], which might be good candidates for the elemental of the DUV laser technology. A further prospect for the basic would be the higher-power fiber laser which could be realized by coherent beam blend with M2 worth under one.

Tunable ultraviolet laser resource based upon good-state dye laser technological innovation and CsLiB6O10 harmonic technology
Its UV absorption edge reaches 180 nm. The effective nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as significant as that of KDP. CLBO crystals is usually developed through the stoichiometric soften with decreased viscosity.
The development of your 193-nm laser was shown by levels of SFG. So as to scale the DUV laser electricity effectively, a brand new idea in the 193-nm DUV laser technology is introduced based upon the diamond Raman laser.
