Equipment was built to align fiber optical ribbons in front of the emitting facet of close-confinement lasers. Typically, 70 of the laser power was transmitted through the fiber with an air gap between laser and fiber approximately 100 was obtained when the gap was filled with an epoxy. Beam-angle data are presented, indicating that a power loss of 30 should be expected for a beam angle of 15 deg cone half-angle an aperture of f1.8. First LOC lasers emit into a cone angle too wide 60 to 90 deg for array applications. Author
