Abstract
An active element for a laser source, the active element comprising an elongated bar with a reflective lateral surface, doped to be able to absorb at least a pumping beam being propagated at least approximately longitudinally in the bar in order to amplify at least a laser radiation also being propagated longitudinally; and a jacket in contact with the lateral surface of the bar and presenting a refractive index smaller than that of the bar, in the reflective lateral surface of the bar, there is at least one dull-ground diffusing zone able to interrupt the paths of spurious laser modes being propagated in the bar by total internal reflections on the lateral surface.
