On this paper, The brand new lapping slurry and polishing slurry are released. As well as the deliquescence diploma of CLBO is fallen to least expensive. A completely new working engineering is usually adopted. Immediately after rough polishing, the concentration of extremely-precision sprucing slurry is elevated appropriately. So does the extremely-precision sharpening pace, plus the wiping pace is quicker in comparison to the deliquescence pace. The CLBO crystal floor roughness can obtain 1nm and hold the surface area top quality nicely. Access via your establishment

According to the proof-of-theory experiment, the conversion efficiency of 23% implied the potential for obtaining superior-power at the second Stokes wavelength of your Raman laser. If your pump laser of 1078 nm could be received at the average ability of fifty W, the output power of its 2nd Stokes wavelength at 1512 nm might be over 10 W. The design of the Raman laser cavity must be optimized in an effort to steer clear of the problems from the M1 and diamond area.
The normal electricity of the NIR laser still has the opportunity being improved to tens of watts including 70 W [26] When the double-go configuration can be used for your Yb:YAG SCF amplifier stage. As a result, Should the conversion efficiency of 31% from NIR to DUV might be continue to maintained at this greater ability condition, the standard output electric power with the DUV laser at 258 nm can be much more than twenty W, which might certainly be a extraordinary ability degree for your DUV laser and bring about the unanticipated DUV laser machining outcomes. In addition, for high-power DUV laser, the UV damage of your nonlinear crystal, such as the windows for CLBO crystal as well as the mirrors, is another important parameter for long-lasting and steady operation.
Conversely, the beam quality of this higher energy DUV laser would turn out to be worse due to extra serious thermal and nonlinear consequences. Hence, the frequency conversion procedures really should be diligently built to mitigate the aforementioned outcomes. Hence, a large-electrical power DUV laser in the FHG of 1 μm with a very good beam excellent may be acquired and will be effective for acquiring the shorter wavelength DUV lasers including 193 nm by SFG.
Each the 1040 nm and 1078 nm laser originate from just one twin-wavelength Yb-doped fiber laser. Every single laser is amplified by stages of fiber amplifier and Yb-doped materials amplifier, respectively.

The heart beat duration of the next Stokes light-weight was shortened to 5 ns as demonstrated in Determine 7a, just one-shot photograph through the oscilloscope, which is a typical phenomenon in Raman laser [forty four] while the pulse length of your pump laser was 10 ns.

Tunable ultraviolet laser resource according to stable-state dye laser know-how and CsLiB6O10 harmonic generation
The conversion effectiveness from essential NIR to DUV is from five% to 36% according to the noted ends in Desk 1. Escalating the conversion effectiveness will check here lessen the stress on the look and set up of the fundamental laser amplifier together with the electric power consumption. A great beam quality of the fundamental laser can even contribute to your growing in the conversion effectiveness and also the suitable electricity intensity in the NIR and eco-friendly laser inside the SHG and FHG approach, respectively. The very best conversion efficiencies from NIR to eco-friendly and eco-friendly to DUV laser by use of CLBO crystal are 70% and around fifty%, respectively [twelve], which corresponds on the conversion effectiveness of 35% from fundamental to DUV.
The development of the 193-nm laser was demonstrated by levels of SFG. In an effort to scale the DUV laser electrical power correctly, a new notion from the 193-nm DUV laser technology is offered depending on the diamond Raman laser.
