Investigation of preionization CO and CO2 lasers operating in the active zone of a stationary nuclear reactor

An experimental study was made of the threshold, energy, spectral, and time characteristics of preionization CO and CO₂ lasers operated in the active zone of a stationary nuclear reactor where the neutron flux density was up to 10¹⁴ cm^–2sec^–1. Continuous emission from a preionization CO laser was obtained for the first time. The laser radiation power reached ~32 W.
