Optically stable, proton-isolated, gain-guided (AlGa)As double heterostructure injection lasers are described. A narrow stripe width (3.5 ..mu..m) and a very shallow implantation are employed (1.3 ..mu..m from the active layer); this results in a cosh/sup -2/-like optical mode of approx.9.0-..mu..m full width at half-maximum. The far-field profiles possess strong sidelobes at high optical output power. The optical material loss coefficient and the antiguiding parameter are derived from the measured far-field profiles, using the theory of gain guiding. Key parameters in the description of the optical mode distribution are calculated for several values of output power.
