چکیده
Dynamic beam shaping brings a large potential for the laser cutting process by increasing speed and improving cut edge quality. However, oscillation is almost exclusively realized with 2-mirror galvanometer scanners that limit industrial implementation of technology. Within this work, new concept platform based on single-mirror scanning system 4 kW fiber tested 12 mm thick plates in different materials. Technology knowledge transfer from existing datasets common has been used to up optimization novel system. The proposed solution able substitute conventional deflection mirrors can be easily integrated into optical path machines. This paper introduces advanced possibilities experimentally demonstrates dynamic performance compared static reference

Robust Capon Beamforming via Shaping Beam Pattern
High sidelobe level and direction of arrival (DOA) estimation sensitivity are two major disadvantages of the Capon beamforming. To deal with these problems, this paper gives an overview of a series of robust Capon beamforming methods via shaping beam pattern, including sparse Capon beamforming, weighted sparse Capon beamforming, mixed norm based Capon beamforming, total variation minimization b...
متن کاملLaser Beam Shaping with Membrane Deformable Mirrors
The performance of laser machining systems can often be improved by adjusting the intensity profile of the beam on the target. Shaping a laser intensity profile can be efficiently accomplished by adjusting the spatial phase of the beam before propagating the beam a distance to the target. Beam shaping can be accomplished with passive diffractive elements, but this technique is only capable of c...

متن کاملLASER CUTTING PARAMETERS The laser cutting parameters are dependent on the beam characteristics, the cutting rate
The laser cutting parameters are dependent on the beam characteristics, the cutting rate required, the composition and thickness of the material to be cut, and the desired cut edge quality. The laser cutting process and cut quality depend upon the proper selection of laser and workpiece parameters. Deficiencies in cutting quality may be related to the slow process drifts and disturbances that a...
