When compared with BBO it features more substantial spectral and temperature acceptance, much better angle tolerance, plus a smaller stroll-off angle. from 3289 $ shipping
Based on the evidence-of-basic principle experiment, the conversion efficiency of 23% implied the possibility of acquiring significant-electrical power at the next Stokes wavelength of your Raman laser. If your pump laser of 1078 nm could possibly be obtained at the average electric power of 50 W, the output ability of its 2nd Stokes wavelength at 1512 nm may be much more than 10 W. The design of the Raman laser cavity need to be optimized to be able to steer clear of the destruction in the M1 and diamond surface.
The common ability on the NIR laser even now has the prospective to become enhanced to tens of watts for example 70 W [26] When the double-go configuration may be utilized for that Yb:YAG SCF amplifier stage. As a result, In case the conversion efficiency of 31% from NIR to DUV might be however taken care of at this higher electric power problem, the standard output electrical power in the DUV laser at 258 nm may be greater than 20 W, which would be described as a remarkable energy degree to the DUV laser and bring on the unanticipated DUV laser machining success. Moreover, for top-energy DUV laser, the UV hurt on the nonlinear crystal, including the Home windows for CLBO crystal as well as mirrors, is another important parameter for long-term and stable operation.

LBO is likewise a great nonlinear crystal which is often applied to the SHG within the NIR into the environmentally friendly. The DUV laser will likely be understood by two stages of SFG while in the LBO crystals considering the fact that there is no section-matching angle for LBO to transform the eco-friendly laser at 515 nm or 532 nm towards the DUV specifically by SHG [sixteen]. Not too long ago, the NSBBF crystal has also proven its probable to acquire a large conversion effectiveness from 532 nm to 266 nm. The stroll-off angle and deff on the NSBBF are Practically just like People of CLBO [17].

While in the scientific and industrial applications, the beam good quality in the DUV laser is additionally an essential parameter. Notably, the beam quality from the DUV laser substantially impacts the laser machining benefits. The beam excellent of your DUV laser is set by that of the fundamental laser and also the crystal to the frequency conversion. A short while ago, a superior-electric power DUV laser (>10 W) at 258 nm was claimed by using a beam top quality of M2 < one.5, which was generated by FHG of the Yb:YAG laser at 1030 nm utilizing the CLBO crystal [13]. This laser would produce an improved laser machining final result in comparison with the previous DUV lasers with much larger M2.
The heartbeat duration of the 2nd Stokes gentle was shortened to 5 ns as revealed in Determine 7a, an individual-shot picture with the oscilloscope, which can be a standard phenomenon in Raman laser [44] though the heartbeat period from the pump laser was ten ns.
