Description
The progressive development of high-power lasers over the last few decades has made it possible to study the generation of gamma radiation by laser-matter interactions. In the limit of ultra-high fields, this process occurs via nonlinear Compton scattering. Gamma-ray bursts are a phenomenon of wide interest, attracting the attention of researchers working in fields ranging from astrophysics to particle physics. Over the last few years, many studies have predicted extremely high conversions of laser energy into gamma-photon energy using various target and/or laser field configurations. The objective of this talk is to discuss several recently proposed gamma-ray burst generation schemes as a guide for upcoming gamma-ray photon experiments and for further development of currently available theoretical schemes, including attosecond gamma-ray bursts and electron-positron pairs, all-optical nonlinear Breit-Wheeler electron-positron pair production using gamma-ray burst photons, and production of electron-positron pairs and radioactive nuclides by irradiating a high-Z target with a gamma-ray burst generated by an ultra-intense laser.
