The key difficulty of ultraviolet coherent light-weight supply predominantly concentrates on the development of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal has become the conditions for frequency transformation, so the growth, dimension, harm resistance, conversion efficiency and allowable parameter selection of nonlinear optical crystal are needed An increasing number of.
Alternatively, the beam quality of the greater power DUV laser would turn out to be worse as a consequence of much more serious thermal and nonlinear consequences. As a result, the frequency conversion processes need to be diligently designed to mitigate the aforementioned outcomes. Thus, a large-ability DUV laser at the FHG of 1 μm with a great beam quality can be attained and can be helpful for obtaining the shorter wavelength DUV lasers which include 193 nm by SFG.

In the scientific and industrial applications, the beam top quality on the DUV laser can be a significant parameter. Notably, the beam good quality in the DUV laser significantly influences the laser machining final results. The beam quality of your DUV laser is set by that of the fundamental laser plus the crystal for your frequency conversion. Recently, a substantial-electric power DUV laser (>ten W) at 258 nm was noted which has a beam good quality of M2 < one.5, which was produced by FHG of the Yb:YAG laser at 1030 nm utilizing the CLBO crystal [13]. This laser would lead to an improved laser machining final result when compared with the former DUV lasers with bigger M2.

Tunable ultraviolet laser resource dependant on stable-point out dye laser know-how and CsLiB6O10 harmonic era
The conversion efficiency from elementary NIR to DUV is from 5% to 36% based on the noted ends in Table 1. Increasing the conversion effectiveness will lessen the burden on the look and set up of the fundamental laser amplifier and also the electrical ability consumption. A superb beam quality of the click here basic laser can even add towards the rising of your conversion efficiency in addition to the suitable ability depth of the NIR and green laser within the SHG and FHG method, respectively. The highest conversion efficiencies from NIR to green and green to DUV laser by usage of CLBO crystal are 70% and all-around fifty%, respectively [twelve], which corresponds for the conversion efficiency of 35% from fundamental to DUV.
