Description
Summary:Nonlinear interaction of strong laser pulses with matter may lead to the excitation of self-consistent motion of charges and generation of a magnetic field, remaining in the plasma after the laser impact. One of the ways to induce azimuthal currents in a specified direction is to break the axial symmetry in the system. Two ways of forming certain direction of motion of charges during interaction are considered; one of them is related to the target structure, and the other is associated with the structure of the laser pulse itself. For the case of super-power multipetawatt femtosecond laser pulses of the XCELS facility, estimates of characteristic parameters are presented, according to which the induction of axial magnetic fields may reach several ten kiloteslas in microcapillary structured targets. In the case of interaction of structured pulses with a homogeneous plasma, an axial magnetic field of the order of several ten teslas may occupy a region of several hundred micrometers in diameter. Schemes of the corresponding experiments are proposed, and possible applications are discussed.
