A tens of Tesla quasi-static axial magnetic field can be produced in the interaction of a short intense laser beam carrying an Orbital Angular Momentum with an underdense plasma. Threedimensional “Particle In Cell” simulations and analytical model demonstrate that orbital angular momentum is transfered from a tightly focused radially polarized laser beam to electrons without any dissipative effect. A theoretical model describing the balistic interaction of electrons with laser shows that…

Inverse Faraday effect with linearly polarized laser pulses.
The inverse Faraday effect is usually associated with circularly polarized radiation; here, we show that it can also occur for linearly polarized radiation. The quasistatic axial magnetic field
GigaGauss solenoidal magnetic field inside bubbles excited in under-dense plasma
This method produces large solenoidal fields that move with the driving laser pulse and are collinear with the accelerated electrons, opening up novel opportunities for designs of the light sources, free electron lasers, and high energy colliders based on laser plasma acceleration.

Magnetization of laser-produced plasma in a chiral hollow target
It is demonstrated that targets with a broken rotational symmetry may facilitate the generation of a strong axial (poloidal) magnetic field. An intense laser beam irradiating such a target creates
