Abstract

Temporally and spatially resolved measurements of inverse Faraday effect (IFE) in a plasma using a self-channeling laser pulse of relativistic intensity were studied. The magnetic fields so obtained were much larger than expected, and have a duration approaching that of the high intensity laser pulse. The simulation results show that the magnetic field is generated by fast electrons which spiral around the axis of the channel created by the laser field.
