Description
The interaction of high-power lasers with targets provides a way to produce γ-photon beams [1,2]. In this work we demonstrate via three-dimensional particle-in-cell simulations a regime where emission of a collimated γ-photon beam occurs for oblique laser incidence angles on the flat target. The electromagnetic field accelerates electrons to the gigaelectronvolt energy level. Consequently, these electrons emit a collimated γ-photon beam when interacting with the electromagnetic field. The dependencies of γ-photon emission on the incident angle, laser polarization, laser power, laser duration and target thickness are addressed. The beam directionality is important for designing future experiments. We visualize the γ-photon emission temporal evolution via our Virtual Beamline - VBL application [3,4,5], accessible in a regular web browser and in a virtual reality headset.
