A study of the characteristics of low voltage arc discharges in cesium vapor led to the development of a practical lamp that was used in a successful communication system using infra-red radiation. The radiated energy is confined almost entirely to the cesium resonance lines at 8521 and 8944 angstroms. Data are presented that give structural details, operating characteristics, infra-red output, and efficiencies of several lamps of different sizes. Excellent modulability is attained throughout the audiofrequency range with current modulation up to 100 percent.
