Laser beam bar, wavelength beam coupling system using laser diode bar, and laser diode bar manufacturing method

摘要

Problem to be solved: to improve the oscillation performance of the wavelength beam coupling system.A laser diode bar used in a wavelength beam coupling system;(0001)AndA nitride semiconductor substrate having a substrate surface having an offset angle greater than 0 degrees to the axis of at least one of the M axis or a axis from the (0001) planeA first conductive cladding layer formed on the nitride semiconductor substrateActive layerA laminated structure comprising a second conductivity type cladding layer andThe emitter direction of the emitter is perpendicular to the principal axis of the off angleTo the laminated structureMultiple emitters formed in stripesLaser diode bar.Diagram
