Abstract
Abstract A gaseous discharge device is connected to a suitable source of electrical energy which may typically be of the pulsed DC type to generate the emission of radiant energy having a determinable spectral character. A magnetic field is caused to perpendicularly intercept the electric field resultant from the flow of current through the gaseous discharge device causing a controllable and predictable change in the spectral character of the emitted radiant energy in accordance with the strength of the magnetic field. By increasing the strength of the magnetic field, two or more peaks of radiant energy of different spectral character may be generated so that peak emitted power may be realized within a desired spectral region to be employed as the excitation energy for a laser, for example.
