Abstract
Energetic electron bunches were generated by irradiating a solid tungsten wire 13μm wide with 50 femtosecond pulses at an intensity of 3×10 18W/cm2. The electron yield, energy spectrum and angular distribution were measured. These energetic electron bunches are suitable for injection into a laser driven plasma accelerator. An all-optical electron injector based on this approach could simplify timing and alignment in future laser-plasma accelerator experiments.
