摘要：
Coupling high-power lasers and high-strength B-fields helps gaining unique insight and understanding of a variety of phenomena of crucial importance for astrophysics and Inertial Confinement Fusion. We have shown that such platform could be used to mimic the expansion of a young star isotropic disk wind threaded by a co-axial poloidal magnetic field. It reveals that long-range collimated jets can indeed by result from such system, complementing toroidal B-fields that help shape the initial matter from the star into a jet. The same system can then be used to study the dynamics of the accretion of magnetized plasma columns onto star surfaces and help decipher the underlying physics, or also the issue of particle energization in astrophysical plasmas. But it can also serve as a test-bed to evaluate the impact of B-fields onto ICF plasmas, a topical subject since it has been recently shown that such magnetization could help increase the temperature of ICF cores, opening a path for potential increase of ICF experiments energy gain.
