Abstract : A general analysis of the performance of a multiple axial cavity constituted by many ruby rods with plane and paralled surfaces has been carried out. The threshold condition for oscillation has been derived by applying a statistical treatment, and the theoretical results have been checked experimentally. A systematic analysis of the spectral output of the laser radiation was carried out together with an analysis of the spiking structure of the pulse. Far and near field patterns have also been studied. The extension of the multiple axial cavity to geometries other than the plane-parallel is briefly discussed. Finally the application of the multiple axial cavity to the production of giant pulse of enhanced monochromaticity has been tested, using glasses with variable transmission coefficient as light-switches.
