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 ( ), 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 ( ) and at least one undoped block ( ), and a process of forming a plurality of active elements from the active rod ( ), said formation process comprising at least one step of transverse cutting along the active rod ( ) and the step of collectively treating surfaces of the active elements, are carried out in succession.
