Abstract

This paper considers various channels of (gamma) -quantum generation via an ultra-short high-power laser pulse interaction with different targets. We analyze the possibilities to create a pulsed (gamma) -radiation source using laser triggering of some nuclear reactions and isomer targets. It is shown that 0.2 MeV monochromatic short pulse of (gamma) -radiation can be obtained with pulse energy sub- mJ level from isomer atoms localized in a magnetic trap. For nuclear reaction channel in light-atom materials, it is shown that 100-TW laser pulse gives rise to formation of about 10⁶ (gamma) -photons near 5 MeV energy.
