Collimated γ-flash emission along the target surface at oblique incidence
Original language description
The interaction of a high-power laser with a solid target enables the generation of γ-photon beams. In this work, we present, through 3D particle-in-cell (PIC) simulations, a regime where, under oblique laser incidence, a collimated γ-photon beam is emitted parallel to the target surface. This process arises from the interference pattern in the electromagnetic field, created by the interaction of the incident and reflected laser pulses. The resulting electromagnetic field accelerates electrons to GeV energy levels while simultaneously directing their momentum along the target surface. As a result, the electrons emit a collimated γ-photon beam in the same direction.
