The invention consists in passing a laser beam () from each of laser sources () through its individual first optical system (), single reflecting this beam () from a substantially flat individual reflecting surface () towards an input facet (') and focusing this beam () by a second common optical system on the input facet (&#x2032;) of the fiber (). The laser beams () are emitted by laser modules (), each containing a single laser source in an individual housing () with a first optical system (), fixed with respect to the housing (). The housing () of each laser module () is mounted in a holder (). The second optical system () is placed directly in front of the input facet (&#x2032;) of the fiber (). An axis () of each first optical system () forms with an axis () of the second optical system () an angle (&#x3b1;) ranging between 45 (&#x3b1;&#x2032;) and 145 (&#x3b1;&#x2033;) degrees. The individual reflecting surfaces () are either on the oblique truncations of rods () placed parallel to the optical axis () of the second optical system () or on the lateral faces of the regular pyramid () with the number of sides of the pyramid base equal to the number of laser modules (). Optical axis () of the second optical system () passes through the vertex and through the center of the base of this pyramid ().
