Paper Abstract

Ten optical fibers were aligned to a single diode laser bar. The fibers were fed through a single optical connector with an aperture diameter of 381 micrometers . Coupling efficiencies as high as 65% were achieved with antireflection-coated fibers approximately 3 cm in length. Over 6.5 W cw at a power density of 5.7 kW/cm2 was delivered from the connector output.
