Inverse Faraday effect in a relativistic laser channel
2001
Laser and particle beams (Print)
Preserved Fulltext
Interaction between energetic electrons and a circularly polarized laser pulse in a relativistic plasma channel is studied. Laser radiation can be resonantly absorbed by electrons executing betatron oscillations in the channel and absorbing angular momentum from the laser. The absorbed angular momentum manifests itself as a strong axial magnetic field inverse Faraday effect!. The magnitude of this magnetic field is calculated and related to the amount of the absorbed energy.
