semiconductor lasers; fiber-optic communications, medicine, and material treatment. SUBSTANCE: laser diode strip whose external end is covered with antireflective coating and rear blind end, with highly reflective coating has laser diodes, cylindrical microlens, and flat external mirror; transversely directed multimode wide- aperture laser diodes are used in strip, their mode of operation being changed from inherent multimode to transversely directed single-mode operation in external resonator wherein laser diodes are synchronized due to diffraction transmission by radiation in reflection from flat external mirror. Common supermode is selected due to inclination of external mirror in p-n junction plane through angle Φ = [(2m+1)lambda/2d] for common supermode and Φ = [mlambda/d] for antiphase one, where m = 0 1, 2 ... . Laser diodes used in strip ensure selection of quarter-Talbot-length common supermode for resonator. EFFECT: enlarged functional capabilities of strip. 7 dwg
