  • Method and device for coupling laser light derived from at least two laser sources into one optical fiber
    Patent number: 9223123
    Abstract: The invention consists in passing a laser beam (3) from each of laser sources (1) through its individual first optical system (4), single reflecting this beam (3) from a substantially flat individual reflecting surface (7) towards an input facet (10?) and focusing this beam (3) by a second common optical system on the input facet (10?) of the fiber (10). The laser beams (3) are emitted by laser modules (1), each containing a single laser source in an individual housing (2) with a first optical system (4), fixed with respect to the housing (2). The housing (2) of each laser module (1) is mounted in a holder (17, 20). The second optical system (9) is placed directly in front of the input facet (10?) of the fiber (10). An axis (12) of each first optical system (3) forms with an axis (13) of the second optical system (9) an angle (?) ranging between 45 (??) and 145 (??) degrees.
