Abstract	Summary form only given. An investigation of high-power broad-stripe lasers and the possibility of their effective coupling with multimode optical fiber was carried out. Laser wafers were grown by a modified LPE (liquid-phase-epitaxy) growth technique utilizing short-term active layer deposition on a moving substrate. Optical fibers with central core diameters of 50, 100, and 200 mu m and NALFA of 0.2 were used for coupling. The maximum values of coupled power for these three fibers were 0.3, 0.39, and 0.44 W for a 1-A driving current through a 60- mu m micrometer-stripe diode. In the case of a 100- mu m-strip diode with 2-A driving current, coupled powers of about 0.7 and 0.9 W were obtained for fibers with 100- and 200- mu m core diameters, respectively.<>
