ABSTRACT:
Silver light reflecting films are formed by depositing on the sides of on quartz glass prism-shaped light transmitters. A copper protective film is formed by depositing on the reflecting film. When laser beams are sequentially applied to the transmitters formed by bundling the transmitters, they repetitively propagate in the transmitters, while being repetitively mirror-reflected by the reflecting films. Since the laser beams are not reflected by total reflection as in the conventional device, an interval between the transmitters can be reduced. Therefore, it can prevent the beam from leaking in emitting the beam.
