抄録

An attosecond high-density electron bunch is produced by an intense short-pulse TEM₁₀+TEM₀₁-mode laser. The transverse ponderomotive force of the TEM₁₀+TEM₀₁-mode laser confines pre-accelerated electrons in the transverse direction, and at the same time the laser longitudinal electric field accelerates the electrons. Our three-dimensional particle simulations show that the pre-accelerated electrons are accelerated to a few hundreds MeV and are compressed to ∼499 attoseconds with a low energy spread (∼±3.5 %). The electron density of the attosecond bunch reaches ∼43 times as high as the initial number density. Such the attosecond electron bunch is now available to attophysics.
