In this paper, the new lapping slurry and sharpening slurry are launched. And the deliquescence degree of CLBO is fallen to most affordable. A whole new Operating technology is additionally adopted. Immediately after tough sprucing, the concentration of ultra-precision sharpening slurry is increased correctly. So does the ultra-precision sharpening velocity, and the wiping velocity is quicker in comparison to the deliquescence pace. The CLBO crystal surface area roughness can accomplish 1nm and keep the surface top quality effectively. Access by means of your establishment

We summarized The present advancement status with the large-power DUV laser both at the wavelength of FHG of your 1-μm laser and at 193 nm. The recent progress in the strong-state/fiber laser, and also the nonlinear optical crystals, prompts not merely the standard electrical power and also the beam high quality (coherence) on the DUV lasers to an unprecedented level.
As an illustration, The present concave OC could be replaced by a plane mirror which could mitigate the facility density about the surface of M1 plus the diamond. Additionally, making use of superior hurt threshold coatings for M1 and diamond would also improve the output electric power without any damages. Then, the NIR laser at the 2nd Stokes wavelength may very well be higher plenty of, and its excellent beam high quality, to generate the ultimate DUV laser at 193 nm with a high ordinary energy.

LBO is additionally a wonderful nonlinear crystal which is usually placed on the SHG from the NIR for the inexperienced. The DUV laser is usually realized by two levels of SFG during the LBO crystals considering that there is no phase-matching angle for LBO to convert the eco-friendly laser at 515 nm or 532 nm to your DUV instantly by SHG [sixteen]. Lately, the NSBBF crystal has also proven its prospective to get a substantial conversion performance from 532 nm to 266 nm. The wander-off angle and deff on the NSBBF are Practically much like those of CLBO [seventeen].

Tunable ultraviolet laser supply determined by reliable-condition dye laser technological innovation and CsLiB6O10 harmonic era
The conversion effectiveness from essential NIR to DUV is from 5% to 36% according to the described results in Desk 1. Rising the conversion efficiency will click here decrease the stress on the design and set up of the fundamental laser amplifier together with the electric ability use. A great beam good quality of the elemental laser will also contribute on the raising in the conversion performance as well as the appropriate electric power depth of your NIR and environmentally friendly laser in the SHG and FHG procedure, respectively. The highest conversion efficiencies from NIR to green and environmentally friendly to DUV laser by usage of CLBO crystal are 70% and all over fifty%, respectively [12], which corresponds towards the conversion performance of 35% from essential to DUV.
