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

We summarized the current enhancement position on the large-electricity DUV laser the two at the wavelength of FHG on the 1-μm laser and at 193 nm. The modern development on the solid-condition/fiber laser, as well as the nonlinear optical crystals, prompts not merely the typical power but in addition the beam high-quality (coherence) from the DUV lasers to an unprecedented degree.

The average ability of your NIR laser however has the likely to become enhanced to tens of watts for example 70 W [26] When the double-go configuration may very well be used for the Yb:YAG SCF amplifier stage. As a result, In the event the conversion performance of 31% from NIR to DUV could possibly be still taken care of at this bigger electrical power affliction, the average output electricity of your DUV laser at 258 nm might be greater than 20 W, which would be described as a extraordinary energy degree to the DUV laser and bring on the unanticipated DUV laser machining success. Moreover, for top-ability DUV laser, the UV damage of your nonlinear crystal, including the Home windows for CLBO crystal plus the mirrors, is yet another significant parameter for long term and secure operation.

However, the beam high-quality of this increased ability DUV laser would grow to be even worse resulting from more significant thermal and nonlinear outcomes. Hence, the frequency conversion processes needs to be meticulously meant to mitigate the aforementioned consequences. Thus, a higher-ability DUV laser at the FHG of one μm with a fantastic beam excellent can be received and can be useful for obtaining the shorter wavelength DUV lasers like 193 nm by SFG.

Each the 1040 nm and 1078 nm laser originate from just one dual-wavelength Yb-doped fiber laser. Each laser is amplified by levels of fiber amplifier and Yb-doped supplies amplifier, respectively.

The conversion efficiency from elementary NIR to DUV is from 5% to 36% in accordance with the noted brings about Table one. Increasing the conversion effectiveness will lessen the burden on the look and set up of the fundamental laser amplifier as well as the electrical ability consumption. A superb beam quality of the fundamental laser can even contribute towards the raising of the conversion efficiency along with the suitable electric power depth with the NIR and eco-friendly laser from the SHG and FHG course of action, respectively. The best conversion efficiencies from NIR to environmentally friendly and inexperienced to DUV laser by utilization of CLBO crystal are 70% and all around 50%, respectively [12], which corresponds to the conversion performance of 35% from elementary to DUV.
