Abstract Laser Module and Method of Coupling an Optical Fiber thereto In a laser module (1) having an optical fiber coupled thereto, the heat sink is formed by a metal block (6) consisting of a base plate (11) with a support for the laser diode (7) and a mounting block (14) for fixing two separate holders (19, 20) for a fiber and sleeve (18). The latter passes through a relatively large opening of the mounting block (14) which is aligned to the laser diode (7). To achieve optimum coupling, after alignment of the fiber end with the laser diode (7) by means of a micro- manipulator, one of the holders (19), e.g. a perforated plate, is fixed to the front of the mounting block (14), after which the sleeve (18) is joined to the holder (19). This is followed by a realignment during which the sleeve (18) can be deflected around the fixing point of the front holder (19). Finally, the other holder (20) is fixed to the rear of the mounting block (14), and the sleeve (18) is joined to this holder (20). (Fig. 1) P.Schmid 6
