With this paper, the new lapping slurry and sprucing slurry are launched. As well as the deliquescence diploma of CLBO is fallen to least expensive. A different Doing work engineering is also adopted. Immediately after tough polishing, the concentration of ultra-precision polishing slurry is enhanced properly. So does the ultra-precision sharpening velocity, along with the wiping velocity is faster in comparison to the deliquescence velocity. The CLBO crystal area roughness can achieve 1nm and retain the surface good quality perfectly. Accessibility as a result of your institution

We summarized The existing progress status of your higher-electrical power DUV laser equally with the wavelength of FHG on the 1-μm laser and at 193 nm. The recent advancement in the sound-state/fiber laser, as well as the nonlinear optical crystals, prompts don't just the typical electric power but also the beam high-quality (coherence) with the DUV lasers to an unprecedented amount.

For illustration, the current concave OC could be replaced by a plane mirror which could mitigate the power density within the surface of M1 and the diamond. Furthermore, working with significant destruction threshold coatings for M1 and diamond would also Enhance the output electricity without any damages. Then, the NIR laser at the 2nd Stokes wavelength may be large more than enough, together with its good beam good quality, to deliver the ultimate DUV laser at 193 nm with a high average ability.

On the other side, the facility scaling with the NIR laser is yet another component to enhance the regular electrical power in the 193-nm DUV laser. As a result of lack of the significant-electrical power amplification solution with the NIR laser (as an example at 1553 nm), nonlinear frequency procedures including optical parameter oscillation (OPO) can be applied to create a wavelength converter by shifting the wavelength from one μm to the specified wavelength along with acquiring relative check here higher electricity [21]. Recently, a diamond Raman laser showed its potential in acquiring a high electrical power and also a superior conversion performance in the 1st Stokes in the one-μm laser [22,23], which suggests the possibility to be used from the 193-nm DUV laser generation on account of its superior Raman gain and huge frequency shift.

Additionally, combining the solid-condition laser with other nonlinear process for instance stimulated Raman scattering, NIR lasers might be realized at new wavelengths with high electrical power and superior beam high quality, which was examined with the evidence-of-basic principle experiment. This Raman laser plan provides a fresh route to the large-electricity DUV laser, Particularly on the wavelength of 193 nm.

The event of the 193-nm laser was demonstrated by levels of SFG. To be able to scale the DUV laser electric power successfully, a different idea on the 193-nm DUV laser technology is presented determined by the diamond Raman laser.
