Generation of a broad-area laser diode is experimentally studied in an external asymmetrical V-cavity comprising an inclined output feedback mirror (FBM) that is nonselective with respect to spectrum and phase. The study is aimed at finding the ranges of a pump current and FBM inclination angles, in which the laser beam is narrow-directed. Laser radiation spectra are measured and FBM angles are juxtaposed with the angles of the output laser beam and the average period of filament positions in the laser diode.
