All-stable-state ultraviolet lasers have already been greatly Employed in the fields of mechanical flaw detection, lithography, micromachining and medication for the advantages of modest quantity, extended existence, large performance, excellent beam high quality, extensive tuning and slim spectral line, and so forth. Utilizing high ability around-infrared coherent light-weight supply as the elemental frequency resource dependant on nonlinear tuning know-how, producing ultraviolet coherent radiation by multistage frequency conversion is viewed as a crucial way to develop the ultraviolet coherent mild supply.

In accordance with the proof-of-theory experiment, the conversion effectiveness of 23% implied the potential of acquiring high-electric power at the 2nd Stokes wavelength of the Raman laser. Should the pump laser of 1078 nm could possibly be obtained at the typical electric power of 50 W, the output energy of its 2nd Stokes wavelength at 1512 nm could be more than 10 W. The design from the Raman laser cavity need to be optimized to be able to steer clear of the hurt of the M1 and diamond area.
The average ability of your NIR laser however has the prospective for being enhanced to tens of watts for example 70 W [26] Should the double-pass configuration may be used for the Yb:YAG SCF amplifier phase. For this reason, In the event the conversion performance of 31% from NIR to DUV could be even now managed at this better electrical power ailment, the normal output ability of the DUV laser at 258 nm may be much more than 20 W, which would certainly be a outstanding electrical power degree for that DUV laser and produce the unanticipated DUV laser machining results. What's more, for top-electrical power DUV laser, the UV hurt of your nonlinear crystal, including the windows for CLBO crystal as well as the mirrors, is another vital parameter for long term and steady operation.

LBO is also a wonderful nonlinear crystal which is often applied to the SHG from your NIR towards the eco-friendly. The DUV laser is usually understood by two stages of SFG inside the LBO crystals since there is absolutely no phase-matching angle for LBO to transform the eco-friendly laser at 515 nm or 532 nm to the DUV immediately by SHG [sixteen]. A short while ago, the NSBBF crystal has also shown its prospective to acquire a significant conversion effectiveness from 532 nm to 266 nm. The walk-off angle and deff of your NSBBF are almost similar to Those people of CLBO [seventeen].

While in the scientific and industrial programs, the beam high quality of your DUV laser is additionally a very important parameter. Specially, the beam good quality from the DUV laser radically influences the laser machining results. The beam excellent of your DUV laser is determined by that of the fundamental laser along with the crystal for your frequency conversion. A short while ago, a large-power DUV laser (>ten W) at 258 nm was reported by using a beam quality of M2 < 1.five, which was created by FHG of the Yb:YAG laser at 1030 nm using the CLBO crystal [13]. This laser would cause a far better laser machining result when compared to the prior DUV lasers with more substantial M2.
Soon after payment, you will receive an e mail with Guidelines along with a link to down load the obtained paper.
Cesium Lithium Borate (CsLiB6O10 or CLBO) get more info is the best non-linear crystal which generates ultraviolet harmonics with the Nd:YAG elementary laser wavelength. So as to improve the harm threshold, minimal CLBO surface roughness, by extremely-precision machining, is necessary. Since the CLBO crystal has straightforward hydroscopic reaction and micro scratches in machining, extremely-exact machining in the CLBO crystal is actually a challenging technological dilemma.
The beam profile proven in Figure 7b demonstrated an excellent beam excellent as among the merits of Raman laser, which would be valuable to crank out a 193-nm DUV laser with a high quality beam.
Its UV absorption edge reaches a hundred and eighty nm. The successful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as substantial as that of KDP. CLBO crystals may be developed through the stoichiometric melt with reduced viscosity.
