A Secret Weapon For CLBO Crystal
In this particular paper, the new lapping slurry and sharpening slurry are introduced. Plus the deliquescence degree of CLBO is fallen to cheapest. A new Performing technologies is additionally adopted. Immediately after rough polishing, the focus of extremely-precision sprucing slurry is amplified thoroughly. So does the extremely-precision sharpening pace, along with the wiping speed is quicker compared to the deliquescence pace. The CLBO crystal floor roughness can realize 1nm and retain the area high-quality perfectly. Accessibility by way of your institutionThere aren't any things inside your cart.

We summarized The existing development position on the substantial-electrical power DUV laser both of those within the wavelength of FHG on the 1-μm laser and at 193 nm. The recent growth from the good-state/fiber laser, and also the nonlinear optical crystals, prompts not just the normal electrical power but additionally the beam quality (coherence) of your DUV lasers to an unprecedented stage.
The standard ability in the NIR laser nevertheless has the prospective to become improved to tens of watts such as 70 W [26] When the double-pass configuration can be used for the Yb:YAG SCF amplifier phase. That's why, When the conversion effectiveness of 31% from NIR to DUV could possibly be still preserved at this bigger energy issue, the average output electrical power of your DUV laser at 258 nm might be greater than 20 W, which might be a extraordinary electrical power stage for your DUV laser and cause the unanticipated DUV laser machining success. Also, for high-electric power DUV laser, the UV damage of the nonlinear crystal, including the Home windows for CLBO crystal and the mirrors, is another significant parameter for long run and stable operation.

On one other facet, the facility scaling in the NIR laser is another aspect to increase the ordinary electric power CLBO Crystal in the 193-nm DUV laser. Due to the not enough the significant-electricity amplification Answer of the NIR laser (for example at 1553 nm), nonlinear frequency processes which include optical parameter oscillation (OPO) may very well be placed on build a wavelength converter by shifting the wavelength from one μm to the specified wavelength and also obtaining relative higher power [21]. Just lately, a diamond Raman laser showed its skill in acquiring a significant ability and a higher conversion efficiency within the 1st Stokes in the 1-μm laser [22,23], which suggests the chance being applied in the 193-nm DUV laser technology thanks to its high Raman obtain and huge frequency change.

Furthermore, combining the stable-state laser with other nonlinear course of action like stimulated Raman scattering, NIR lasers can be accomplished at new wavelengths with significant power and large beam excellent, which was analyzed by the proof-of-principle experiment. This Raman laser scheme delivers a new path to the high-energy DUV laser, Particularly on the wavelength of 193 nm.
