The typical power of your NIR laser continue to has the likely for being enhanced to tens of watts for instance 70 W [26] In the event the double-pass configuration can be utilized with the Yb:YAG SCF amplifier stage. That's why, When the conversion performance of 31% from NIR to DUV might be however taken care of at this bigger electrical power condition, the common output ability from the DUV laser at 258 nm may be over twenty W, which might certainly be a remarkable power degree for your DUV laser and produce the unanticipated DUV laser machining outcomes. What's more, for high-electric power DUV laser, the UV damage in the nonlinear crystal, such as the Home windows for CLBO crystal as well as mirrors, is yet another important parameter for lasting and stable operation.
Alternatively, the beam quality of this better energy DUV laser would develop into even worse as a result of additional really serious thermal and nonlinear effects. That's why, the frequency conversion procedures should be cautiously intended to mitigate the aforementioned outcomes. So, a high-energy DUV laser on the FHG of 1 μm with an excellent beam top quality might be acquired and will be advantageous for getting the shorter wavelength DUV lasers for instance 193 nm by SFG.
Both equally the 1040 nm and 1078 nm laser originate from a single dual-wavelength Yb-doped fiber laser. Each laser is amplified by levels of fiber amplifier and Yb-doped resources amplifier, respectively.

Right after payment, you'll acquire an e mail with Guidelines along with a connection to download the ordered paper.
Furthermore, combining the stable-state laser with click here other nonlinear course of action such as stimulated Raman scattering, NIR lasers may be obtained at new wavelengths with large ability and higher beam top quality, which was examined because of the evidence-of-basic principle experiment. This Raman laser plan delivers a completely new path to the superior-ability DUV laser, especially at the wavelength of 193 nm.

The event in the 193-nm laser was shown by stages of SFG. In an effort to scale the DUV laser power properly, a new notion with the 193-nm DUV laser generation is presented determined by the diamond Raman laser.
