New Step by Step Map For CLBO Crystal
Blog Article
During this paper, the new lapping slurry and polishing slurry are launched. As well as deliquescence degree of CLBO is fallen to most affordable. A brand new Doing work technologies is also adopted. Just after rough polishing, the concentration of ultra-precision polishing slurry is increased correctly. So does the ultra-precision sharpening velocity, plus the wiping velocity is faster than the deliquescence pace. The CLBO crystal area roughness can achieve 1nm and hold the surface top quality well.

The average electricity in the NIR laser even now has the prospective to become improved to tens of watts including 70 W [26] if the double-move configuration might be used for your Yb:YAG SCF amplifier phase. As a result, if the conversion efficiency of 31% from NIR to DUV can be still taken care of at this greater power affliction, the normal output ability from the DUV laser at 258 nm can be much more than twenty W, which might be a remarkable power degree for the DUV laser and lead to the unanticipated DUV laser machining results. Furthermore, for prime-electricity DUV laser, the UV hurt in the nonlinear crystal, such as the Home windows for CLBO crystal and also the mirrors, is another essential parameter for long term and steady Procedure.

LBO is usually a great nonlinear crystal which is usually placed on the SHG from the NIR for the environmentally friendly. The DUV laser is generally understood by two stages of SFG inside the LBO crystals due to the fact there isn't any stage-matching angle for LBO to convert the green laser at 515 nm or 532 nm towards the DUV immediately by SHG [16]. Not too long ago, the NSBBF crystal has also proven its prospective to obtain a high conversion efficiency from 532 nm to 266 nm. The wander-off angle and deff with the NSBBF are Practically much like These of CLBO [seventeen].

Tunable ultraviolet laser resource dependant on solid-point out dye laser technology and CsLiB6O10 harmonic technology
Its UV absorption edge reaches one hundred eighty nm. The successful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as substantial as that of KDP. CLBO crystals could be developed with the stoichiometric melt with decreased viscosity.
The development with the 193-nm laser was demonstrated by phases of SFG. So that you can scale the DUV laser electrical power correctly, a fresh strategy of the check here 193-nm DUV laser generation is offered dependant on the diamond Raman laser.
