Abstract: Topic1: Quasi-single-cycle relativistic laser pulse generation by laser-foil interaction
Speaker:Wenmin Zhang
Abstract: A scheme for producing nearly single-cycle relativistic laser pulses is proposed.When a laser pulse interacts with an overdense thin foil, because of self-consistent nonlinear modulation the latter will be more transparent to the more-intense part of the laser, so that a transmitted pulse can be much shorter than the incident pulse.Using particle-in-cell simulation and analytical modeling, it is found that a transmitted pulse of duration 4 fs can be generated from a circularly polarized laser pulse.
