On this paper, the new lapping slurry and polishing slurry are released. And the deliquescence diploma of CLBO is fallen to least expensive. A new working technology can be adopted. Soon after rough sprucing, the concentration of ultra-precision polishing slurry is improved adequately. So does the extremely-precision sharpening speed, plus the wiping pace is faster as opposed to deliquescence pace. The CLBO crystal surface roughness can achieve 1nm and keep the floor good quality properly. Entry through your establishment

According to the proof-of-theory experiment, the conversion performance of 23% implied the possibility of attaining significant-ability at the 2nd Stokes wavelength of the Raman laser. When the pump laser of 1078 nm might be received at the common energy of fifty W, the output power of its 2nd Stokes wavelength at 1512 nm might be a lot more than 10 W. The look on the Raman laser cavity needs to be optimized to be able to avoid the harm from the M1 and diamond surface.
The normal electric power from the NIR laser even now has the possible for being improved to tens of watts for example 70 W [26] If your double-pass configuration could be utilized for the Yb:YAG SCF amplifier stage. Therefore, Should the conversion effectiveness of 31% from NIR to DUV can be even now managed at this higher electricity condition, the common output ability from the DUV laser at 258 nm may be more than 20 W, which would be described as a remarkable energy degree for that DUV laser and bring on the unanticipated DUV laser machining results. Furthermore, for high-energy DUV laser, the UV hurt in the nonlinear crystal, including the windows for CLBO crystal as well as the mirrors, is another important parameter for long-lasting and steady operation.

Due to the thermal lens influence within the stable-point out lasers, In case the read more heating administration is insufficient, It's not at all straightforward to obtain the good-state laser by using a superior electric power and a higher beam good quality concurrently. Not long ago, with the event of The skinny disk laser and solitary-crystal fiber (SCF) laser, a significant-electric power laser at the elemental wavelength (one μm) were understood with an excellent beam high-quality In spite of a TEM00 manner beam [4,24], which would be great candidates for the basic on the DUV laser era. A different applicant for the basic could be the significant-electric power fiber laser which could be achieved by coherent beam mix with M2 worth under 1.

The beam profile revealed in Determine 7b demonstrated a great beam good quality as on the list of deserves of Raman laser, which might be beneficial to crank out a 193-nm DUV laser with a top quality beam.
