Gain measurement in the He-I(+) laser
Abstract
The gain of some visible transitions of the excited iodine ion was examined using a 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.
