Optical coupler between light conductor and semiconductor laser - has emitting surface at same height as conducting core with module set in path

摘要

Optical coupler placed between a wire shaped light conductor and a semi-conductor laser. The conductor and laser are mounted on a support with the light inlet and outlet surfaces on a common optical axis. The light path between the semiconductor laser and the wire shaped light conductor incorporates another optical module. The light emitting surface of the active laser zone of the semiconductor laser (2) is at the same height as the light conducting core (5) of the light conductor (4). The module in the light path of the conductor and the laser is part of a circular cylindrical light conductor, whose longitudinal axis is at right angles to the longitudinal axis of the first light conductor. The focal line is in the output plane of the semiconductor laser.
