Collimated ultrabright gamma rays from electron wiggling along a petawatt laser-irradiated wire in the QED regime
Collimated ultrabright gamma rays from electron wiggling along a petawatt laser-irradiated wire in the QED regime
Significance Even though bright X-rays below mega-electron volt photon energy can be obtained from X-ray free electron lasers and synchrotron radiation facilities, it remains a great challenge to generate collimated bright gamma-ray beams over 10 mega-electron volts. We propose a scheme to efficiently generate such beams from submicron wires irradiated …
