| Research Abstract |
It has been demonstrated that electrons are generated and accelerated in the interaction of an intense femtosecond laser pulse with a metal fine wire and the electrons are guided along the wire and emitted from the wire end with high directivity. The electron guiding is realized even for a 1m wire, and the electrons with energies of hundreds of keV and directivity of tens of mrad are emitted. Numerical simulations reveal that the electrons are trapped by the transient electric field surrounding the wire and guided along the axial direction.
