During this paper, The brand new lapping slurry and sprucing slurry are launched. As well as deliquescence diploma of CLBO is fallen to least expensive. A completely new Doing the job technological innovation is additionally adopted. Following tough sharpening, the concentration of extremely-precision sharpening slurry is improved effectively. So does the ultra-precision polishing pace, plus the wiping pace is faster as opposed to deliquescence pace. The CLBO crystal area roughness can achieve 1nm and keep the area good quality effectively. Access through your establishment

We summarized The present improvement status with the substantial-electric power DUV laser equally for the wavelength of FHG of the one-μm laser and at 193 nm. The current enhancement in the sound-state/fiber laser, plus the nonlinear optical crystals, prompts don't just the common electric power but will also the beam quality (coherence) of the DUV lasers to an unparalleled stage.
The true secret trouble of ultraviolet coherent light-weight resource mainly concentrates on the development of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is amongst the circumstances for frequency transformation, so The expansion, measurement, harm resistance, conversion performance and allowable parameter choice of nonlinear optical crystal are necessary more and more.
On the other hand, the beam good quality of the larger ability DUV laser would grow to be even worse as a consequence of a lot more really serious thermal and nonlinear effects. Consequently, the frequency conversion procedures really should be carefully created to mitigate the aforementioned results. As a result, a superior-power DUV laser at the FHG of one μm with a good beam high quality could possibly be acquired and will be advantageous for obtaining the shorter wavelength DUV lasers which include 193 nm by SFG.
Both of those the 1040 nm and 1078 nm laser originate from just one dual-wavelength Yb-doped fiber laser. Every laser is amplified by stages of fiber amplifier and Yb-doped products amplifier, respectively.
On another aspect, the power scaling of the NIR laser is yet another aspect to increase the average ability with the 193-nm DUV laser. Due to insufficient the superior-electric power amplification Remedy of your NIR laser (by way of example at 1553 nm), nonlinear frequency processes for instance optical parameter oscillation (OPO) could possibly be placed on create a wavelength converter by shifting the click here wavelength from 1 μm to the desired wavelength and obtaining relative better energy [21]. Not long ago, a diamond Raman laser confirmed its capability in obtaining a significant energy along with a substantial conversion effectiveness for the 1st Stokes of your one-μm laser [22,23], which implies the possibility for being utilized from the 193-nm DUV laser era as a consequence of its significant Raman get and huge frequency shift.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the most effective non-linear crystal which generates ultraviolet harmonics of the Nd:YAG essential laser wavelength. So as to increase the injury threshold, low CLBO floor roughness, by ultra-precision machining, is necessary. Since the CLBO crystal has easy hydroscopic response and micro scratches in machining, extremely-exact machining with the CLBO crystal is actually a difficult complex problem.
Tunable ultraviolet laser supply depending on sound-state dye laser technologies and CsLiB6O10 harmonic technology
