Within this paper, the new lapping slurry and sharpening slurry are introduced. As well as the deliquescence degree of CLBO is fallen to most affordable. A completely new Performing technologies is likewise adopted. After rough sharpening, the focus of ultra-precision polishing slurry is elevated effectively. So does the ultra-precision sharpening pace, along with the wiping pace is faster compared to deliquescence pace. The CLBO crystal surface area roughness can accomplish 1nm and maintain the area top quality properly. Entry by way of your institution

We summarized the current progress standing of the significant-electricity DUV laser the two on the wavelength of FHG from the one-μm laser and at 193 nm. The modern improvement of your sound-state/fiber laser, together with the nonlinear optical crystals, prompts not only the common power but in addition the beam quality (coherence) in the DUV lasers to an unprecedented stage.
For example, the current concave OC could get replaced by a airplane mirror which could mitigate the power density on the area of M1 along with the diamond. Furthermore, using significant injury threshold coatings for M1 and diamond would also Increase the output electric power without any damages. Then, the NIR laser for the 2nd Stokes wavelength could possibly be high ample, in addition to its excellent beam high-quality, to produce the ultimate DUV laser at 193 nm which has a high ordinary electricity.

The two the 1040 nm and 1078 nm laser come from one twin-wavelength Yb-doped fiber laser. Each and every laser is amplified by levels of fiber amplifier and Yb-doped products amplifier, respectively.
On the other facet, the ability scaling in the NIR laser is another component to improve the common ability with the 193-nm DUV laser. Due to insufficient the higher-electrical power amplification Answer of your NIR laser (such as at 1553 nm), nonlinear frequency processes such as optical parameter oscillation (OPO) may very well be placed on make a wavelength converter by shifting the wavelength from one μm to the desired wavelength along with getting relative higher electrical power [21]. A short while ago, a diamond Raman laser confirmed its capacity in accomplishing a high electrical power in addition to a here high conversion efficiency in the 1st Stokes of the 1-μm laser [22,23], which means the chance to be applied from the 193-nm DUV laser technology thanks to its high Raman gain and large frequency change.

The beam profile demonstrated in Determine 7b shown a very good beam high quality as one of several deserves of Raman laser, which would be useful to crank out a 193-nm DUV laser with a top quality beam.

The development of the 193-nm laser was demonstrated by stages of SFG. In order to scale the DUV laser ability efficiently, a completely new idea on the 193-nm DUV laser technology is offered based upon the diamond Raman laser.
