In this particular paper, The brand new lapping slurry and polishing slurry are launched. Plus the deliquescence diploma of CLBO is fallen to lowest. A new Functioning technological know-how is usually adopted. Right after rough sharpening, the concentration of extremely-precision polishing slurry is improved adequately. So does the ultra-precision sharpening speed, as well as wiping speed is faster compared to the deliquescence speed. The CLBO crystal area roughness can reach 1nm and retain the floor high quality well. Obtain as a result of your establishment

We summarized the current improvement position on the higher-ability DUV laser equally in the wavelength of FHG with the 1-μm laser and at 193 nm. The latest development of the stable-state/fiber laser, together with the nonlinear optical crystals, prompts don't just the typical electricity but will also the beam high-quality (coherence) with the DUV lasers to an unprecedented stage.
By way of example, The present concave OC could be replaced by a airplane mirror which could mitigate the ability density around the area of M1 plus the diamond. Additionally, applying superior destruction threshold coatings for M1 and diamond would also Enhance the output electrical power with none damages. Then, the NIR laser for the 2nd Stokes wavelength could possibly be significant adequate, as well as its good beam high quality, to deliver the final DUV laser at 193 nm having a superior normal power.

LBO is likewise a great nonlinear crystal which is usually placed on the SHG from your NIR into the inexperienced. The DUV laser is frequently understood by two phases of SFG inside the LBO crystals considering the fact that there is absolutely no section-matching angle for LBO to transform the green laser at 515 nm or 532 nm for the DUV right by SHG [sixteen]. Lately, the NSBBF crystal has also revealed its potential to acquire a high conversion efficiency from 532 nm to 266 nm. The stroll-off angle and deff from the NSBBF are Pretty much just like Those people of CLBO [seventeen].

In addition, combining the strong-point out laser with other nonlinear course of action such as stimulated Raman scattering, NIR lasers could possibly be realized at new wavelengths with high energy and large beam good quality, which was tested because of the proof-of-principle experiment. This Raman laser scheme offers a fresh route to the high-electrical power DUV laser, Specially at the wavelength of 193 nm.
This cookie is utilized to record the input contents as well as the progress in the input type. It does not keep any own data.
Its UV absorption edge reaches 180 nm. The effective nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as massive as that of KDP. CLBO crystals might be developed website through the stoichiometric melt with decreased viscosity.
