| 英文摘要 | A semiconductor laser unit (2) includes a plurality of semiconductor laser elements (4,5) arranged parallel with one another in a laser beam-emitting direction, and a base (T1) for positioning and fixing the plurality of semiconductor laser elements (4,5). The plurality of semiconductor laser elements (4,5) are arranged such that a laser beam (14) emitted from the semiconductor laser element (4) greatest in astigmatism, of the plurality of semiconductor laser elements (4,5), is coincident in its axis with a reference axis (S1) of the base (T1). In the case that the semiconductor laser unit (2) is arranged on an optical head device (1), the focusing characteristic on the plurality of laser beams (14,16) can be improved. |
