Spontaneous and induced emission of excimer molecules under pumping of and gas mixtures with a low content by fast electrons and uranium fission fragments

Abstract

The spontaneous and induced emission of excimer molecules upon excitation of and gas mixtures with a low content by high-energy charged particles [a pulsed high-energy electron beam and products of neutron nuclear reaction ] has been experimentally studied. The electron energy was , and the pump current pulse duration and amplitude were and , respectively. The energy of fission fragments did not exceed , the duration of the neutron pump pulse was , and the specific power contribution to the gas was about . Electron beam pumping in a cell long with a cavity having an output mirror transmittance of 2.7% gives rise to lasing on the transition in the molecule with a gain and fluorescence efficiency . Pumping by fission fragments in a -long cell with a cavity formed by a highly reflecting mirror and a quartz window implements amplified spontaneous emission (ASE) with an output power of and a base ASE pulse duration of .
