| 摘要 |
The present invention relates to a laser light source module that makes it possible to distribute currents equally to a plurality of LD elements, while suppressing the divergence angles of light beams. In the laser light source module, an LD array includes a plurality of arrayed LDs (4), each submount includes a first conductive pattern (122a) that is connected to one electrode (8) of each LD and a second conductive pattern (123a) that is connected to the other electrode (2), a first power supply point (222a) on a first-power-supply-terminal side is provided on a first-end side, with respect to the array direction of the LDs, in the first conductive pattern, and a second power supply point (223a) on a second-power-supply-terminal side is provided on a second-end side, with respect to the array direction, in the second conductive pattern. |
