APPARATUS FOR INVESTIGATING STIMULATED EMISSION FROM TRANSVERSE DISCHARGES IN PURE METAL VAPORS.

A description is given of apparatus with a sectioned anode and a common heated-container cathode for investigating transverse pulse discharges in pure metal vapors emitting stimulated radiation as a result of atomic and ionic transitions. It is reported that a system of anode sections each with its own storage capacitor but with a common cathode and switch can ensure stable and homogeneous discharges over a wide range of pressures. The results are reported of an investigation of the dependence of the properties of stimulated radiation emitted from Sr ii ions ( lambda equals 430. 5 nm) on the discharge parameters.
