On this paper, the new lapping slurry and sharpening slurry are launched. And also the deliquescence diploma of CLBO is fallen to most affordable. A new Doing the job engineering is additionally adopted. After tough sharpening, the concentration of ultra-precision sharpening slurry is improved properly. So does the extremely-precision sharpening pace, and also the wiping speed is quicker when compared to the deliquescence pace. The CLBO crystal surface area roughness can realize 1nm and hold the surface quality effectively. Obtain by means of your establishment

We summarized the current improvement position of your high-power DUV laser both of those for the wavelength of FHG from the one-μm laser and at 193 nm. The recent progress from the stable-state/fiber laser, in addition to the nonlinear optical crystals, prompts not simply the typical electric power but also the beam good quality (coherence) of your DUV lasers to an unparalleled amount.
For example, The existing concave OC could get replaced by a plane mirror which could mitigate the facility density to the surface area of M1 as well as the diamond. Furthermore, using significant injury threshold coatings for M1 and diamond would also Enhance the output energy with no damages. Then, the NIR laser within the 2nd Stokes wavelength may very well be substantial sufficient, as well as its good beam excellent, to create the ultimate DUV laser at 193 nm with a large normal electrical power.

Equally the 1040 nm and 1078 nm laser come from one particular dual-wavelength Yb-doped fiber laser. Each and every laser is amplified by stages of fiber amplifier and Yb-doped supplies amplifier, respectively.
On another side, the power scaling of your NIR laser is yet another factor to boost the average ability on the 193-nm DUV laser. As a result of not enough the substantial-energy amplification Alternative of your NIR laser (by way of example at 1553 nm), nonlinear frequency procedures for instance optical parameter oscillation (OPO) could be applied to make a wavelength converter by shifting the wavelength from 1 μm to the specified wavelength as well as acquiring relative higher ability [21]. A short while ago, a diamond Raman laser confirmed its skill in achieving a substantial electrical power in addition to a substantial conversion effectiveness at the 1st Stokes from the one-μm laser [22,23], which implies the check here possibility to become utilized inside the 193-nm DUV laser generation on account of its high Raman achieve and huge frequency shift.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics in the Nd:YAG fundamental laser wavelength. To be able to enhance the problems threshold, lower CLBO surface roughness, by extremely-precision machining, is needed. As the CLBO crystal has straightforward hydroscopic response and micro scratches in machining, ultra-specific machining on the CLBO crystal is actually a tough technological trouble.
Tunable ultraviolet laser resource dependant on good-condition dye laser technology and CsLiB6O10 harmonic generation
