With the development of ultra-intense laser technology, MeV ions can be obtained from laser-foil interactions in the laboratory. These energetic ion beams can be applied in fast ignition for inertial confinement fusion, medical therapy, and proton imaging. However, these ions are mainly accelerated in the laser propagation direction. Ion acceleration in an azimuthal orientation was scarcely stu...

Poor surface quality represents an important issue that needs improvement for metal Additively Manufactured parts. Both short or long wavelength lasers have been applied polishing in order to improve the finish. In this work, possible use of a CO2 laser AlSi10Mg parts made by Laser-based Powder Bed Fusion (L-PBF) was explored. The high roughness as-built condition can lead increased energy abso...

The feasibility of a new approach of laser fusion in plasma without implosion has been proposed and is discussed using an intense laser. The cross section of the nuclear reaction is increased by enhancing the penetrability of nuclei through the Coulomb barrier. In this approach, an intense laser field of more than 100 PW was required to distort the Coulomb barrier to obtain enough penetrability...

The hydrodynamic scaling relations are of great importance for the design and optimization target compression in laser-driven fusion. In this paper, we propose an artificially intelligent method to construct implosion velocity areal density direct-drive fast ignition by combining one-dimensional simulations machine learning methods. It is found that a large fuel mass high required high-gain fus...

Startup companies are betting on different approaches and laser technologies for fusion to become a commercially viable energy source.

Abstract Fusion energy research is delivering impressive new results emerging from different infrastructures and industrial devices evolving rapidly ideas to proof-of-principle demonstration aiming at the conceptual design of reactors for production electricity. A major milestone has recently been announced in laser fusion by Lawrence Livermore National Laboratory giving thrust laser-fusion wor...
