Abstract
According to this method, in order to fabricate active elements which comprise at least one doped part comprising a doping capable of absorbing a pump beam and at least one undoped part, and which have opposed faces of the same geometrical shape, a process of preparing an elongate active rod (5), which has a cross section identical to said geometrical shape, said process comprising at least one step of cutting and one step of joining at least one doped block (6) and at least one undoped block (7, 8), and a process of forming a plurality of active elements from the active rod (5), said formation process comprising at least one step of transverse cutting along the active rod (5) and the step of collectively treating surfaces of the active elements, are carried out in succession.
