Acceleration of charged particles by ultrashort light pulses which create a space-charge front at the axis of a channel in a medium
Askar'yan G. A.
The entry of an intense ultrashort light pulse into a channel in a medium causes charged plasma to form by relativistic photoelectrons. At the leading edge of this plasma, longitudinal field ^ 1 GV/cm can arise. These fields could be utilized to accelerate particles to energies δ; 1 GeV. The energies and lengths which the light pulses would have to have are estimated.
