All-strong-state ultraviolet lasers are extensively used in the fields of mechanical flaw detection, lithography, micromachining and medicine for the advantages of small quantity, prolonged everyday living, superior performance, excellent beam excellent, huge tuning and slim spectral line, and so forth. Using higher electricity in close proximity to-infrared coherent gentle resource as the basic frequency resource dependant on nonlinear tuning technological know-how, creating ultraviolet coherent radiation by multistage frequency conversion is regarded as an essential technique to create the ultraviolet coherent gentle resource.

The normal electricity in the NIR laser nevertheless has the possible to generally be enhanced to tens of watts like 70 W [26] if the double-move configuration may be utilized with the Yb:YAG SCF amplifier phase. Consequently, When the conversion performance of 31% from NIR to DUV may be nevertheless managed at this increased energy ailment, the typical output ability in the DUV laser at 258 nm may be more than 20 W, which would become a amazing power level for your DUV laser and bring about the unanticipated DUV laser machining effects. Moreover, for high-power DUV laser, the UV damage of the nonlinear crystal, such as the Home windows for CLBO crystal and also the mirrors, is yet another important parameter for lasting and secure operation.

Then again, the beam quality of this larger energy DUV laser would turn into even worse on account of much more really serious thermal and nonlinear effects. For this reason, the frequency conversion procedures needs to be diligently created to mitigate the aforementioned outcomes. Thus, a higher-electrical power DUV laser with the FHG of one μm with a superb beam excellent can be attained and may be valuable for acquiring the shorter wavelength DUV lasers for example 193 nm by SFG.

The beam profile revealed in Figure 7b shown a great beam good quality as one of the merits of Raman laser, which would be useful to crank out a 193-nm DUV laser more info with a top quality beam.
