  • Coupling between laser and optical fiber
    Patent number: 4475788
    Abstract: In order to focus the beam of a laser onto a receiving end of an optical fiber substantially coaxial therewith, the laser output is formed by a planoconvex lens with a semitransparent flat face confronting the laser cavity and an antireflecting curved face turned toward the fiber. Alignment of the laser beam with the fiber axis is accomplished by the adjustment of two oppositely pointing juxtaposed wedges interposed between the lens and the laser.
