Figure 1 (IMAGE) Osaka University Caption Efficient high energy electron generation by interfering multiple laser beamlets. (a) Experimentally observed interference pattern, (b) Electromagnetic field energy obtained by the corresponding PIC simulation, (c) Electron energy spectra measured in the experiment. The total laser incident energies are same in 1 beamlet and 4 beamlets cases.
