On this paper, The brand new lapping slurry and sprucing slurry are launched. As well as deliquescence degree of CLBO is fallen to cheapest. A completely new Functioning know-how is also adopted. Right after rough sharpening, the concentration of extremely-precision sprucing slurry is amplified properly. So does the extremely-precision sprucing pace, plus the wiping pace is faster as opposed to deliquescence pace. The CLBO crystal surface roughness can attain 1nm and keep the area excellent very well. Accessibility via your establishment

The key problem of ultraviolet coherent gentle resource predominantly concentrates on the event of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal has become the disorders for frequency transformation, so The expansion, sizing, damage resistance, conversion performance and allowable parameter number of nonlinear optical crystal are expected Increasingly more.
Conversely, the beam top quality of the greater ability DUV laser would turn out to be even worse on account of more critical thermal and nonlinear outcomes. Hence, the frequency conversion processes needs to be thoroughly meant to mitigate the aforementioned consequences. Thus, a higher-electrical power DUV laser at the FHG of 1 μm with a good beam high quality might be obtained and will be effective for getting the shorter wavelength DUV lasers for instance 193 nm by SFG.
The two the 1040 nm and 1078 nm laser come from a person twin-wavelength Yb-doped fiber laser. Every single laser is amplified by levels of fiber amplifier and Yb-doped components amplifier, respectively.
On the opposite aspect, the power scaling of the NIR laser is yet another factor to raise the typical power of your 193-nm DUV laser. Mainly because of the insufficient the superior-electric power amplification solution of your NIR laser (by way of example at 1553 nm), nonlinear frequency processes which include optical parameter oscillation (OPO) may be placed on develop a wavelength converter by shifting the wavelength from one μm to the specified wavelength along with getting relative greater electric power [21]. Not long ago, a diamond Raman laser confirmed its ability in accomplishing a large electric power and a higher conversion effectiveness with the 1st Stokes of your one-μm laser [22,23], which means the chance to generally be used during the 193-nm DUV laser technology as a consequence of its superior Raman acquire and huge frequency shift.

Also, combining the strong-condition laser with other nonlinear process for example stimulated Raman scattering, NIR lasers might be reached at new wavelengths with high electrical power and high beam top quality, which was examined because of the evidence-of-basic principle experiment. This Raman laser scheme delivers a brand new route to the higher-ability DUV laser, Particularly on the wavelength of 193 nm.
Tunable ultraviolet laser supply based on stable-state dye laser know-how and CsLiB6O10 harmonic era
Its UV absorption edge reaches 180 nm. The helpful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as big get more info as that of KDP. CLBO crystals can be developed from your stoichiometric soften with decreased viscosity.
The development of the 193-nm laser was demonstrated by levels of SFG. To be able to scale the DUV laser electric power successfully, a completely new strategy from the 193-nm DUV laser era is introduced according to the diamond Raman laser.
