Optimization of nuclear-pumped laser active media by electron beam

In present report there are assumed the results of nuclear pumped laser (NPL) active media experimental studying with electron beam excitation and the analysis is made for emission characteristics and kinetic processes of more perspective lasers, which are operating at low pumping power close to NPL excitation conditions. Basic attention is paying to experimental data, obtained for e‐beam pumped low‐threshold active media, which have allowed to accelerate the understanding of the inversion population creation processes in NPL and which have predetermined new future experiments with NPL. It has been shown that in spit of same differences in plasma creation processes for e‐beam pumping and fission fragment excitation, operating level and inversion population creation processes in nonequilibrium recombinant plasma are similar for both types of excitation at compatible pumping power and pulse duration.
