Abstract

This paper considers various channels of gamma-quantum generation via an ultra-short high-power laser pulse interaction with different targets.We analyse the possibilities to create a pulsed gamma-radiation source using laser triggering of some nuclear reactions and isomer targets. It is shown that sub-MeV monochromatic short pulse of gamma-radiation can be obtained with pulse energy of sub-mJ level from isomer target irradiated by intense laser pulse. For nuclear reaction channel in lightatom materials, it is shown that sub-PW laser pulse gives rise to formation about million gamma-photons of multi-MeV energy.
