According to the proof-of-theory experiment, the conversion effectiveness of 23% implied the possibility of acquiring high-power at the 2nd Stokes wavelength in the Raman laser. Should the pump laser of 1078 nm might be acquired at the standard electric power of 50 W, the output energy of its 2nd Stokes wavelength at 1512 nm could possibly be over 10 W. The look of your Raman laser cavity need to be optimized in order to avoid the hurt in the M1 and diamond surface area.
The standard power on the NIR laser still has the probable being enhanced to tens of watts like 70 W [26] Should the double-pass configuration could be utilized with the Yb:YAG SCF amplifier stage. Hence, if the conversion effectiveness of 31% from NIR to DUV could possibly be even now managed at this larger electrical power ailment, the typical output ability of your DUV laser at 258 nm may be greater than 20 W, which might certainly be a exceptional electric power amount with the DUV laser and result in the unanticipated DUV laser machining benefits. Also, for top-ability DUV laser, the UV destruction of the nonlinear crystal, such as the Home windows for CLBO crystal as well as the mirrors, is an additional crucial parameter for lasting and steady Procedure.
However, the beam high-quality of this bigger electric power DUV laser would come to be worse resulting from much more critical thermal and nonlinear consequences. Therefore, the frequency conversion procedures ought to be meticulously intended to mitigate the aforementioned results. Consequently, a high-electrical power DUV laser for the FHG of one μm with a good beam top quality may very well be received and may be advantageous for obtaining the shorter wavelength DUV lasers for example 193 nm by SFG.

Tunable ultraviolet laser supply according website to reliable-condition dye laser technological innovation and CsLiB6O10 harmonic era
The conversion effectiveness from essential NIR to DUV is from 5% to 36% based on the reported leads to Desk one. Growing the conversion effectiveness will lessen the stress on the design and setup of the basic laser amplifier along with the electrical ability consumption. An excellent beam top quality of the basic laser may even add into the growing on the conversion performance together with the right ability depth of your NIR and environmentally friendly laser in the SHG and FHG process, respectively. The best conversion efficiencies from NIR to environmentally friendly and environmentally friendly to DUV laser by utilization of CLBO crystal are 70% and close to 50%, respectively [twelve], which corresponds on the conversion efficiency of 35% from elementary to DUV.
