We summarized the current improvement standing of the superior-electrical power DUV laser both equally for the wavelength of FHG of your 1-μm laser and at 193 nm. The recent advancement of your strong-condition/fiber laser, and also the nonlinear optical crystals, prompts don't just the common energy and also the beam good quality (coherence) of your DUV lasers to an unparalleled level.
The average electrical power on the NIR laser even now has the potential to become enhanced to tens of watts such as 70 W [26] If your double-go configuration could possibly be used to the Yb:YAG SCF amplifier stage. Therefore, In the event the conversion performance of 31% from NIR to DUV may be even now maintained at this larger ability problem, the normal output ability in the DUV laser at 258 nm can be greater than 20 W, which would be described as a extraordinary energy amount for that DUV laser and result in the unanticipated DUV laser machining outcomes. In addition, for prime-ability DUV laser, the UV harm on the nonlinear crystal, such as the windows for CLBO crystal as well as the mirrors, is another essential parameter for long-term and stable Procedure.
However, the beam quality of the higher electricity DUV laser would become even worse because of additional significant thermal and nonlinear outcomes. Consequently, the frequency conversion processes must be cautiously created to mitigate the aforementioned outcomes. Hence, a superior-electric power DUV laser with the FHG of 1 μm with a superb beam good quality might be obtained and may be beneficial for acquiring the shorter wavelength DUV lasers including 193 nm by SFG.
LBO is additionally a great nonlinear crystal which is usually applied to the SHG in the NIR on the inexperienced. The DUV laser will likely be understood by two levels of SFG during the LBO crystals since there isn't any phase-matching angle for LBO to transform the environmentally friendly laser at 515 nm or 532 nm into the DUV right by SHG [sixteen]. Just lately, the NSBBF crystal has also proven its probable to acquire a substantial conversion efficiency from 532 nm to 266 nm. The walk-off angle and deff from the NSBBF are Practically much like People of CLBO [17].

During the scientific and industrial purposes, the beam excellent of the DUV laser is likewise a crucial parameter. Particularly, the beam excellent from the DUV laser drastically impacts the laser machining results. The beam good quality of the DUV laser is set by that of the basic laser plus the crystal for the frequency conversion. Just lately, a significant-power DUV laser (>10 W) at 258 nm was claimed having click here a beam good quality of M2 < one.five, which was generated by FHG of a Yb:YAG laser at 1030 nm using the CLBO crystal [13]. This laser would result in a far better laser machining outcome compared to the prior DUV lasers with larger sized M2.
Just after payment, you can acquire an e-mail with Directions along with a hyperlink to down load the acquired paper.
Also, combining the strong-condition laser with other nonlinear system including stimulated Raman scattering, NIR lasers can be realized at new wavelengths with high electrical power and significant beam good quality, which was examined from the proof-of-theory experiment. This Raman laser scheme supplies a completely new route to the substantial-electric power DUV laser, Primarily at the wavelength of 193 nm.
The beam profile shown in Determine 7b demonstrated a superb beam quality as among the merits of Raman laser, which would be effective to crank out a 193-nm DUV laser with a top quality beam.
