Abstract

The search for promising ways of nuclear energy usage has led to the emergence of a whole line of research on the direct conversion of the nuclear reaction products energy into laser radiation. In the present work, the amplifying properties of a spatially inhomogeneous nuclear-excited containing uranium nanoparticles moving argon-xenon medium irradiated by an inhomogeneous neutron field were studied. This work purpose is to investigate the dependence of the laser active medium amplifying properties on the initial gas mixture velocity, neutron pulse duration, and the neutron flux space-time distribution. As a short result, we could present the radial dependence of the laser radiation intensity gain at different points in time showed on the picture below. Summarizing laser radiation intensity gain calculations results: an active laser- medium with a length of 1 m provides a significant amplification (10 or more times) of the laser radiation in one pass. And it seems to be reasonable to continue studying the amplifying properties of such laser-active medium, considering the laser radiation’s wave nature.
