During this paper, the new lapping slurry and polishing slurry are launched. As well as deliquescence degree of CLBO is fallen to lowest. A different working engineering is likewise adopted. Just after tough sprucing, the focus of extremely-precision sharpening slurry is elevated appropriately. So does the extremely-precision sharpening speed, as well as the wiping speed is quicker than the deliquescence velocity. The CLBO crystal floor roughness can accomplish 1nm and continue to keep the area excellent properly. Accessibility through your establishment

Based on the evidence-of-principle experiment, the conversion performance of 23% implied the potential of reaching substantial-ability at the 2nd Stokes wavelength of the Raman laser. When the pump laser of 1078 nm might be acquired at the typical energy of fifty W, the output electric power of its 2nd Stokes wavelength at 1512 nm could be more than ten W. The look in the Raman laser cavity needs to be optimized in order to steer clear of the problems with the M1 and diamond area.
For instance, The existing concave OC could get replaced by a airplane mirror which could mitigate the ability density over the surface of M1 and the diamond. Moreover, applying high problems threshold coatings for M1 and diamond would also improve the output ability with none damages. Then, the NIR laser with the 2nd Stokes wavelength might be superior adequate, and its excellent beam top quality, to deliver the final DUV laser at 193 nm by using a high common ability.

On another side, the facility scaling on the NIR laser is another aspect to enhance the regular energy of the 193-nm DUV laser. Due to the not enough the large-electrical power amplification solution on the NIR laser (for instance at 1553 nm), nonlinear frequency procedures such as optical parameter oscillation (OPO) may very well be placed on develop a wavelength converter by shifting the wavelength from one μm to the specified wavelength in addition to acquiring relative increased power [21]. Just lately, a diamond Raman laser confirmed its ability in attaining a significant ability along with a large conversion effectiveness at the 1st Stokes of the 1-μm laser [22,23], which means the chance to become applied within the 193-nm DUV laser generation because of its higher Raman acquire and large frequency change.

Inside the scientific and industrial programs, the beam top quality from the DUV laser can also be an essential parameter. Especially, the beam quality of your DUV laser considerably influences the laser machining benefits. The beam high quality of your DUV laser is set by that of the fundamental laser plus the crystal for your frequency conversion. A short while ago, a high-electric power DUV laser (>10 W) at 258 nm was described having a beam good quality of M2 < one.5, which was produced by FHG of the Yb:YAG laser at 1030 nm utilizing the CLBO crystal [13]. This laser would bring on a greater laser machining consequence compared to the earlier DUV lasers with much larger M2.

Also, combining the strong-condition laser with other nonlinear approach such as stimulated Raman scattering, NIR lasers may be obtained at new wavelengths with higher power and large beam good quality, which was analyzed via the evidence-of-basic principle experiment. This Raman laser plan presents a brand new route to the higher-electrical power DUV laser, Specially with the wavelength of 193 nm.

The event of the 193-nm laser was demonstrated by phases of SFG. So that you website can scale the DUV laser energy properly, a completely new idea on the 193-nm DUV laser technology is introduced based on the diamond Raman laser.
