All-good-point out ultraviolet lasers are broadly Utilized in the fields of mechanical flaw detection, lithography, micromachining and medication for the advantages of tiny quantity, long life, superior performance, fantastic beam good quality, large tuning and slim spectral line, and so forth. Utilizing significant electric power around-infrared coherent light resource as the basic frequency source according to nonlinear tuning technologies, building ultraviolet coherent radiation by multistage frequency conversion is considered an important strategy to develop the ultraviolet coherent mild resource.

We summarized The existing enhancement standing of the large-ability DUV laser both equally for the wavelength of FHG from the one-μm laser and at 193 nm. The the latest growth on the stable-state/fiber laser, along with the nonlinear optical crystals, prompts don't just the normal electricity but additionally the beam high-quality (coherence) in the DUV lasers to an unprecedented level.
The typical electricity with the NIR laser still has the possible to be improved to tens of watts including 70 W [26] if the double-go configuration could be used to the Yb:YAG SCF amplifier stage. Hence, If your conversion efficiency of 31% from NIR to DUV may very well be however maintained at this greater power situation, the typical output energy of the DUV laser at 258 nm may very well be greater than twenty W, which would be a impressive electric power level for your DUV laser and result in the unanticipated DUV laser machining results. Moreover, for high-energy DUV laser, the UV destruction of the nonlinear crystal, such as the Home windows for CLBO crystal as well as the mirrors, is another significant parameter for long lasting and secure Procedure.

On another side, the ability scaling in the NIR laser is another facet to boost the average ability of your 193-nm DUV laser. Due to the not enough the substantial-electrical power amplification Alternative on the NIR laser (as an example at 1553 nm), nonlinear frequency procedures like optical parameter oscillation (OPO) could possibly be placed on develop a wavelength converter by shifting the wavelength from one μm to the desired wavelength together with obtaining relative increased ability [21]. Not long ago, a diamond Raman laser showed its potential in attaining a significant electrical power and also a superior conversion efficiency at the 1st Stokes from the 1-μm laser [22,23], which suggests the chance to be used within the 193-nm DUV laser era as a result of its significant Raman attain and enormous frequency shift.

Within the scientific and industrial applications, the beam top quality on the DUV laser is likewise a crucial parameter. Significantly, the beam high-quality with the DUV laser considerably influences the laser machining final results. The beam quality of the DUV laser is decided by that of the elemental laser along with the crystal for your frequency conversion. Recently, a significant-electrical power DUV laser (>ten W) at 258 nm was noted which has a beam good quality of M2 < one.five, which was created by FHG of a Yb:YAG laser at 1030 nm utilizing the CLBO crystal [thirteen]. This laser would result in an even better laser machining result as compared to the earlier DUV lasers with much larger M2.
The heart beat period of the 2nd Stokes light-weight was shortened to five ns as shown in Figure 7a, an individual-shot photograph in the oscilloscope, which happens to be a standard phenomenon in Raman laser [forty four] although the pulse period with the pump laser was ten ns.
Furthermore, combining the strong-point out laser with other nonlinear approach like stimulated Raman scattering, NIR lasers may very well be attained at new wavelengths with high electric power and higher beam high-quality, which was examined because of the evidence-of-basic principle experiment. This Raman laser plan offers a whole new path to the superior-electricity DUV laser, website especially on the wavelength of 193 nm.

Its UV absorption edge reaches 180 nm. The helpful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as large as that of KDP. CLBO crystals is often grown from the stoichiometric melt with lessen viscosity.
