Abstract
A laser diode in the form of a chip with a heat sink connected to an electronic control circuit, is positioned in front of a light conductor for emitting light into the light conductor. The light conductor (103), such as a fiber (101) of a glass fiber cable (102), passes through a hole in the wall of a housing (100) for the electronic control circuit. The light conductor end is precisely adjusted in the Z-direction of an X-Y-Z-coordinate system, and rigidly held in the adjusted position in a bore or slot (17a) of a mounting block (17). The laser diode (10) with its chip (11) and its heat sink (12) are held in a roughly adjusted position in a milled recess (17c) of the mounting block (17) relative to the tip of the light conductor by a compression leaf spring (14) which permits an adjustment of the laser diode with its chip and heat sink in the X- and Y-direction for a precise adjustment. A displacement gripper tongue mechanism is then used for a precise position adjustment in the X- and Y-direction. After the precise adjustment the laser diode with its chip and heat sink are spot welded by a laser beam to the mounting block. Preferably, a cooling body in heat transfer contact with the heat sink forms a unitary, integral, one piece structure with the mounting block.
