Abstract
The gain of some visible transitions of the excited iodine ion was examined using frequency selective absorption technique. This method can be used to find optimum discharge parameters in the lasing medium. As an example the positive column He−I+ system was studied. The results were compared with a simple theory of discharge radiation propagating along the axis of the discharge tube.
