A Secret Weapon For CLBO Crystal
A Secret Weapon For CLBO Crystal
Blog Article
On this paper, The brand new lapping slurry and sprucing slurry are introduced. Along with the deliquescence diploma of CLBO is fallen to least expensive. A different Operating technological innovation is likewise adopted. Soon after tough sharpening, the concentration of ultra-precision polishing slurry is improved adequately. So does the extremely-precision sharpening pace, plus the wiping velocity is faster in comparison to the deliquescence pace. The CLBO crystal surface area roughness can attain 1nm and retain the surface area top quality nicely. Obtain as a result of your establishment

For instance, The existing concave OC could get replaced by a aircraft mirror which could mitigate the facility density around the surface of M1 as well as the diamond. Furthermore, using significant injury threshold coatings for M1 and diamond would also Increase the output energy with no damages. Then, the NIR laser in the 2nd Stokes wavelength may be large enough, together with its excellent beam good quality, to produce the final DUV laser at 193 nm using a superior common electric power.

Both the 1040 nm and 1078 nm laser originate from a person twin-wavelength Yb-doped fiber laser. Every single laser is amplified by phases of fiber amplifier and Yb-doped elements amplifier, respectively.

Soon after payment, you may get an electronic mail with Recommendations plus a website link to down load the ordered paper.
Furthermore, combining the stable-state laser with other nonlinear approach such as stimulated Raman scattering, NIR lasers may be achieved at new wavelengths with large electric power and high beam good quality, which was analyzed from the proof-of-theory experiment. This Raman laser scheme supplies a different path to the large-energy DUV laser, Specifically on the wavelength of 193 nm.
The beam profile revealed in Figure 7b demonstrated an excellent beam excellent as one of the merits of Raman laser, which would be advantageous to create a 193-nm DUV laser with a high quality beam.
The conversion efficiency read more from basic NIR to DUV is from 5% to 36% based on the claimed leads to Desk one. Escalating the conversion performance will reduce the load on the look and set up of the fundamental laser amplifier plus the electrical power intake. An excellent beam excellent of the elemental laser will also contribute for the rising with the conversion performance and the right ability depth of your NIR and environmentally friendly laser during the SHG and FHG system, respectively. The best conversion efficiencies from NIR to inexperienced and eco-friendly to DUV laser by use of CLBO crystal are 70% and around fifty%, respectively [12], which corresponds towards the conversion efficiency of 35% from elementary to DUV.
