All-reliable-point out ultraviolet lasers have been extensively used in the fields of mechanical flaw detection, lithography, micromachining and medication for the advantages of modest quantity, prolonged life, superior effectiveness, good beam excellent, huge tuning and slender spectral line, and so on. Using substantial electricity in the vicinity of-infrared coherent gentle source as the fundamental frequency supply according to nonlinear tuning engineering, creating ultraviolet coherent radiation by multistage frequency conversion is viewed as a very important technique to develop the ultraviolet coherent light-weight supply.

In comparison to BBO it options bigger spectral and temperature acceptance, better angle tolerance, and also a more compact walk-off angle. from 3289 $ shipping

For illustration, the current concave OC could get replaced by a aircraft mirror which could mitigate the power density within the surface area of M1 along with the diamond. In addition, making use of significant injury threshold coatings for M1 and diamond would also improve the output electric power without any damages. Then, the NIR laser in the 2nd Stokes wavelength may be substantial more than enough, as well as its great beam high quality, to produce the final DUV laser at 193 nm using a high typical power.

Both of those the 1040 nm and 1078 nm laser originate from a read more single dual-wavelength Yb-doped fiber laser. Each laser is amplified by phases of fiber amplifier and Yb-doped components amplifier, respectively.

During the scientific and industrial apps, the beam excellent on the DUV laser can be a vital parameter. Notably, the beam high quality of the DUV laser radically affects the laser machining outcomes. The beam quality of your DUV laser is set by that of the fundamental laser as well as crystal to the frequency conversion. Lately, a superior-electricity DUV laser (>ten W) at 258 nm was documented with a beam good quality of M2 < one.5, which was produced by FHG of the Yb:YAG laser at 1030 nm utilizing the CLBO crystal [thirteen]. This laser would bring about a far better laser machining consequence in comparison to the preceding DUV lasers with larger sized M2.

The beam profile proven in Figure 7b shown a good beam high quality as on the list of deserves of Raman laser, which would be advantageous to make a 193-nm DUV laser with a high quality beam.
