All-strong-condition ultraviolet lasers are already greatly Employed in the fields of mechanical flaw detection, lithography, micromachining and drugs for the benefits of smaller quantity, prolonged lifestyle, superior effectiveness, good beam top quality, vast tuning and slender spectral line, etc. Utilizing significant energy in close proximity to-infrared coherent light-weight resource as the basic frequency resource based upon nonlinear tuning technological know-how, creating ultraviolet coherent radiation by multistage frequency conversion is regarded as a very important method to establish the ultraviolet coherent light resource.
As compared to BBO it options much larger spectral and temperature acceptance, better angle tolerance, as well as a scaled-down wander-off angle. from 3289 $ supply
Based on the evidence-of-principle experiment, the conversion effectiveness of 23% implied the opportunity of achieving large-electric power at the second Stokes wavelength from the Raman laser. When the pump laser of 1078 nm can be obtained at the average energy of 50 W, the output power of its 2nd Stokes wavelength at 1512 nm could be much more than ten W. The look on the Raman laser cavity must be optimized so as to stay away from the problems with the M1 and diamond surface area.
The common electric power with the NIR laser even now has the prospective to generally be enhanced to tens of watts for example 70 W [26] In case the double-pass configuration could possibly be used to the Yb:YAG SCF amplifier stage. Hence, Should the conversion effectiveness of 31% from NIR to DUV could be even now preserved at this higher electricity condition, the typical output power in the DUV laser at 258 nm can be greater than 20 W, which would be described as a impressive power stage with the DUV laser and result in the unanticipated DUV laser machining benefits. Moreover, for high-electricity DUV laser, the UV problems of the nonlinear crystal, including the Home windows for CLBO crystal as well as mirrors, is yet another critical parameter for long run and stable Procedure.

Both the 1040 nm and 1078 nm laser originate from a single dual-wavelength Yb-doped fiber laser. Every single laser is amplified by stages of fiber amplifier and Yb-doped components amplifier, respectively.

In addition, combining the solid-state laser with other nonlinear course of action including stimulated Raman scattering, NIR lasers can be reached at new wavelengths with high electrical power and superior beam high quality, which was tested with the evidence-of-theory experiment. This Raman laser scheme supplies a completely new path to the higher-electrical power DUV laser, In particular at the wavelength of 193 nm.
