Pulse and continuous stimulated emission was obtained from a preionization CO 2 laser operating in the active zone of a stationary nuclear reactor. A gas mixture of the CO 2 :N 2 : 3 He = 1:4:5 composition was ionized by the products of the 3 He ( n, p ) T reaction. The parameters of a non-self-sustaining discharge excited in the active region were determined and the threshold characteristics were found of an atmospheric-pressure laser preionized by fluxes up to 10 14 neutrons·cm –2 ·sec –1 .
