Abstract

Giant half-cycle attosecond pulse generation in the coherent bremsstrahlung emission regime is proposed for laser pulses with normal incidence on a double-foil target, where the first foil is transparent and the second foil is opaque. The presence of the second opaque target contributes to the formation of a relativistic flying electron sheet (RFES) from the first foil target. After the RFES has passed through the second opaque target, it is decelerated sharply, and bremsstrahlung emission occurs, which results in the generation of an isolated half-cycle attosecond pulse having an intensity of 1.4×1022W/cm2 and a duration of 3.6 as. The generation mechanism does not require extra filters and may open a regime of nonlinear attosecond science.
