The diode laser structure in order has the beam parameter product where fiber connection is optimized, to form the diode laser beam

摘要

The SA axis of the aforementioned striped emitter is lined up in the same direction the plural striped emitters which the parallel are done (31 - 38) the diode laser structure which it has in (2), the said striped emitter is arranged shifting mutually in particular direction, at least the plural striped emitters (31 - 38), the respective beam parameter product which designates the SA axis as standard (BPP _SA) differs. According to this invention, the aforementioned striped emitter (31 - 38), the beam parameter product which designates the SA axis as standard (BPP _SA), the mirror surface decreases symmetrically the diode laser structure (2) from the center the said diode laser structure (2) facing toward both edge, especially the diode laser structure (2) with the center as a standard.
