As an illustration, the current concave OC could get replaced by a aircraft mirror which could mitigate the facility density to the floor of M1 and also the diamond. Furthermore, working with substantial problems threshold coatings for M1 and diamond would also Enhance the output electrical power with none damages. Then, the NIR laser with the 2nd Stokes wavelength could be higher enough, and its excellent beam top quality, to deliver the ultimate DUV laser at 193 nm that has a significant average energy.

Each the 1040 nm and 1078 nm laser come from a single twin-wavelength Yb-doped fiber laser. Just about every laser is amplified by stages of fiber amplifier and Yb-doped products amplifier, respectively.

During the scientific and industrial purposes, the beam excellent in the DUV laser can also be an important parameter. Specially, the beam top quality of your DUV laser dramatically has an effect on the laser machining benefits. The beam quality on the DUV laser is decided by that of the fundamental laser along with the crystal with the frequency conversion. Not too long ago, a significant-electricity DUV laser (>ten W) at 258 nm was claimed by using a beam quality of M2 < 1.5, which was produced by FHG of the Yb:YAG laser at 1030 nm utilizing the CLBO crystal [13]. This laser would cause a greater laser machining outcome as compared to the previous DUV lasers with greater read more M2.

The pulse length of the second Stokes mild was shortened to five ns as shown in Figure 7a, only one-shot image within the oscilloscope, which can be a standard phenomenon in Raman laser [forty four] although the heart beat period in the pump laser was ten ns.

Moreover, combining the good-state laser with other nonlinear procedure for example stimulated Raman scattering, NIR lasers can be obtained at new wavelengths with high electricity and significant beam high quality, which was tested via the evidence-of-theory experiment. This Raman laser scheme provides a completely new path to the substantial-electrical power DUV laser, Specifically in the wavelength of 193 nm.

Tunable ultraviolet laser supply based on solid-condition dye laser technological know-how and CsLiB6O10 harmonic technology

Its UV absorption edge reaches a hundred and eighty nm. The efficient nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about twice as massive as that of KDP. CLBO crystals is often developed through the stoichiometric soften with reduce viscosity.

The development of your 193-nm laser was shown by levels of SFG. So as to scale the DUV laser electric power correctly, a brand new idea in the 193-nm DUV laser technology is offered determined by the diamond Raman laser.
