All-sound-condition ultraviolet lasers are greatly Employed in the fields of mechanical flaw detection, lithography, micromachining and medication for the benefits of tiny quantity, lengthy existence, large efficiency, good beam quality, wide tuning and narrow spectral line, etc. Using higher electrical power around-infrared coherent light-weight source as the elemental frequency source based on nonlinear tuning technology, building ultraviolet coherent radiation by multistage frequency conversion is considered an important strategy to develop the ultraviolet coherent mild supply.
When compared to BBO it functions much larger spectral and temperature acceptance, better angle tolerance, as well as a smaller walk-off angle. from 3289 $ shipping and delivery
In accordance with the proof-of-theory experiment, the conversion effectiveness of 23% implied the potential of attaining substantial-electric power at the 2nd Stokes wavelength of your Raman laser. Should the pump laser of 1078 nm may be acquired at the standard electric power of 50 W, the output ability of its 2nd Stokes wavelength at 1512 nm could possibly be greater than ten W. The design of your Raman laser cavity must be optimized to be able to stay away from the damage from the M1 and diamond floor.
The common power on the NIR laser still has the opportunity to become improved to tens of watts such as 70 W [26] If your double-move configuration could be utilized for that Yb:YAG SCF amplifier phase. Therefore, If your conversion efficiency of 31% from NIR to DUV might be even now preserved at this increased ability ailment, the average output power from the DUV laser at 258 nm could be more than twenty W, which might become a impressive electricity stage to the DUV laser and produce the unanticipated DUV laser machining success. What's more, for top-electricity DUV laser, the UV injury from the nonlinear crystal, such as the windows for CLBO crystal and also the mirrors, is yet another vital parameter for long run and secure operation.

LBO is likewise a wonderful nonlinear crystal which is usually applied to the SHG in the NIR to your environmentally friendly. The DUV laser will likely be understood by two levels of SFG in the LBO crystals given that there is absolutely no stage-matching angle for LBO to transform the environmentally friendly laser at 515 nm or 532 nm towards the DUV directly by SHG [sixteen]. Lately, the NSBBF crystal has also proven its probable to get a substantial conversion effectiveness from 532 nm to 266 nm. The walk-off angle and deff of the NSBBF are Pretty much comparable to those of CLBO [seventeen].

While in the scientific and industrial apps, the beam good quality of your DUV laser is likewise an important parameter. Especially, the beam quality on the DUV laser drastically impacts the laser machining outcomes. The beam excellent on the DUV laser is set by that of the fundamental laser and also the crystal to the frequency conversion. A short while ago, a large-electric power DUV laser (>10 W) at 258 nm was documented by using a beam top quality of M2 < one.5, which was generated by FHG of the Yb:YAG laser at 1030 nm using the CLBO crystal [thirteen]. This laser would result in a far better laser machining result in comparison with the former DUV lasers with much larger M2.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics in the Nd:YAG website basic laser wavelength. In order to greatly enhance the hurt threshold, reduced CLBO area roughness, by ultra-precision machining, is required. Because the CLBO crystal has uncomplicated hydroscopic reaction and micro scratches in machining, ultra-specific machining in the CLBO crystal is a hard technological difficulty.
