We summarized the current development status in the superior-energy DUV laser equally within the wavelength of FHG of the 1-μm laser and at 193 nm. The new development from the strong-state/fiber laser, in addition to the nonlinear optical crystals, prompts not simply the typical electricity and also the beam quality (coherence) from the DUV lasers to an unprecedented amount.
The normal power of your NIR laser continue to has the probable to get enhanced to tens of watts including 70 W [26] if the double-move configuration could possibly be utilized for that Yb:YAG SCF amplifier stage. Consequently, Should the conversion effectiveness of 31% from NIR to DUV might be even now preserved at this bigger power situation, the typical output electrical power on the DUV laser at 258 nm may very well be much more than twenty W, which would be considered a amazing electricity degree for your DUV laser and result in the unanticipated DUV laser machining final results. Furthermore, for top-power DUV laser, the UV damage of your nonlinear crystal, including the windows for CLBO crystal plus the mirrors, is an additional essential parameter for long-lasting and steady Procedure.

While in the scientific and industrial programs, the beam high quality of the DUV laser is usually a significant parameter. Specifically, the beam quality of your DUV laser substantially has an effect on the laser machining benefits. The beam quality on the DUV laser is decided by that of the basic laser as well as crystal for the frequency conversion. Just lately, a high-electricity DUV laser (>ten W) at 258 nm was reported by using a read more beam quality of M2 < 1.5, which was produced by FHG of the Yb:YAG laser at 1030 nm utilizing the CLBO crystal [thirteen]. This laser would bring about an improved laser machining final result when compared with the prior DUV lasers with larger M2.

Also, combining the solid-state laser with other nonlinear approach which include stimulated Raman scattering, NIR lasers might be reached at new wavelengths with significant ability and superior beam quality, which was tested because of the evidence-of-theory experiment. This Raman laser scheme provides a new route to the significant-electrical power DUV laser, Specially for the wavelength of 193 nm.

The conversion effectiveness from fundamental NIR to DUV is from five% to 36% based on the noted brings about Table one. Expanding the conversion efficiency will lessen the burden on the design and set up of the elemental laser amplifier plus the electrical ability consumption. A superb beam high-quality of the fundamental laser may also lead on the expanding of your conversion performance as well as the appropriate energy intensity in the NIR and eco-friendly laser inside the SHG and FHG course of action, respectively. The best conversion efficiencies from NIR to environmentally friendly and inexperienced to DUV laser by utilization of CLBO crystal are 70% and close to 50%, respectively [12], which corresponds for the conversion efficiency of 35% from essential to DUV.
