Compared to BBO it functions larger sized spectral and temperature acceptance, far better angle tolerance, in addition to a smaller walk-off angle. from 3289 $ shipping and delivery
We summarized The present improvement position on the large-power DUV laser both equally on the wavelength of FHG of your one-μm laser and at 193 nm. The current enhancement in the solid-condition/fiber laser, as well as the nonlinear optical crystals, prompts not merely the average electrical power but will also the beam high quality (coherence) with the DUV lasers to an unparalleled amount.
The typical electrical power from the NIR laser still has the opportunity to generally be improved to tens of watts which include 70 W [26] In the event the double-go configuration may very well be utilized for that Yb:YAG SCF amplifier stage. For this reason, In the event the conversion performance of 31% from NIR to DUV could possibly be still preserved at this larger electrical power affliction, the typical output electricity of the DUV laser at 258 nm could possibly be in excess of twenty W, which would become a amazing ability level for the DUV laser and bring about the unanticipated DUV laser machining final results. Also, for top-ability DUV laser, the UV destruction of the nonlinear crystal, such as the windows for CLBO crystal and the mirrors, is another important parameter for long-lasting and secure Procedure.

LBO is additionally a wonderful nonlinear crystal which is always applied to the SHG with the NIR to the eco-friendly. The DUV laser is frequently understood by two levels of SFG while in the LBO crystals since there's no stage-matching angle for LBO to convert the green laser at 515 nm or 532 nm to the DUV straight by SHG [16]. Lately, the NSBBF crystal has also shown its possible to obtain a high conversion performance from 532 nm to 266 nm. The wander-off angle and deff with the NSBBF are Just about just like Individuals of CLBO [17].

In the scientific and industrial purposes, the beam excellent with the DUV laser is likewise a significant parameter. Specially, the beam good quality with the DUV laser dramatically has an effect on the laser machining benefits. The beam high quality of the DUV laser is set by that of the fundamental laser plus the crystal to the frequency conversion. Lately, a significant-electrical power DUV laser (>ten W) at 258 nm was noted using a beam quality of M2 < 1.5, which was created by FHG of the Yb:YAG laser at 1030 nm utilizing the CLBO crystal [13]. This laser would bring on a greater laser machining end result compared to the earlier DUV lasers with much larger M2.

The beam profile proven in Figure 7b shown a very good beam quality as one of several merits of Raman laser, which might be effective to generate a 193-nm DUV laser with a high quality beam.

The event from the 193-nm laser was shown by levels of SFG. In an effort to scale the DUV laser power properly, a new principle of your 193-nm DUV laser generation is offered based upon the diamond Raman laser.
