Abstract
A laser element assembly used in an optical disk apparatus or others is made up of a laser element for emitting a laser beam and a holder for holding the laser element, and it is required to set the traveling direction of the laser beam accurately to a desired direction when the laser element assembly is incorporated in the optical disk apparatus. In a laser element assembly according to the present invention, the laser emitting surface of the holder is made perpendicular to the traveling direction of the laser beam and is attached to the optical disk apparatus. Thus, the traveling direction of the laser beam can be accurately arranged in relation to a reference plane of the optical disk apparatus. Further, in a method of fabricating a laser element assembly in accordance with the present invention, a laser element is operated so as to emit a laser beam, and a machining operation is performed for the laser emitting surface of a holder in a state that the laser beam is emitted from the laser element, to make the laser emitting surface perpendicular to the traveling direction of the laser beam.
