All-sound-state ultraviolet lasers are already broadly Utilized in the fields of mechanical flaw detection, lithography, micromachining and drugs for the benefits of small quantity, extensive everyday living, significant effectiveness, excellent beam high-quality, extensive tuning and slim spectral line, etcetera. Making use of large power around-infrared coherent gentle supply as the fundamental frequency supply determined by nonlinear tuning technological innovation, creating ultraviolet coherent radiation by multistage frequency conversion is considered an essential way to acquire the ultraviolet coherent gentle source.

According to the proof-of-principle experiment, the conversion efficiency of 23% implied the opportunity of achieving large-electric power at the 2nd Stokes wavelength of your Raman laser. If the pump laser of 1078 nm might be attained at the standard ability of fifty W, the output electric power of its 2nd Stokes wavelength at 1512 nm can be more than ten W. The design in the Raman laser cavity needs to be optimized as a way to avoid the damage of your M1 and diamond floor.
The common electrical power in the NIR laser nonetheless has the potential to generally be improved to tens of watts like 70 W [26] if the double-move configuration could be used for your Yb:YAG SCF amplifier phase. As a result, If your conversion effectiveness of 31% from NIR to DUV might be continue to preserved at this higher electric power ailment, the common output electrical power with the DUV laser at 258 nm could be a lot more than 20 W, which would become a extraordinary power level for your DUV laser and bring about the unanticipated DUV laser machining effects. Moreover, for top-ability DUV laser, the UV harm in the nonlinear crystal, including the windows for CLBO crystal along with the mirrors, is an additional critical parameter for lasting and steady Procedure.

While in the scientific and industrial apps, the beam high-quality from the DUV laser is additionally a vital parameter. Specially, the beam excellent on the DUV laser substantially impacts the laser machining outcomes. The beam high quality of your DUV laser is set by that of the basic laser as well as crystal to the frequency conversion. Recently, a significant-electrical power DUV laser (>ten W) at 258 nm was described using a beam top quality of M2 < 1.5, which was produced by FHG of a Yb:YAG laser at 1030 nm using the CLBO crystal [13]. This laser would bring on a far better laser machining consequence when compared to the previous DUV lasers with greater M2.
