MULTIPLEXER, MULTIPLEXING METHOD, AND LD MODULE |
摘要 |
A multiplexer includes: an output section outputting a beam bundle made of a plurality of laser beams whose F-axis directions are aligned; and an F-axis converging lens causing the beam bundle outputted from the output section to be converged in the F-axis direction. Optical axes of the plurality of laser beams constituting the beam bundle outputted from the output section intersect with each other at a single point without relying on the F-axis converging lens. |

1. A multiplexer comprising:
an output section outputting a beam bundle made of a plurality of laser beams whose optical axes are contained in a single plane, each of the plurality of laser beams having an F-axis that is not orthogonal to the single plane; and a converging lens converging the beam bundle outputted from the output section, extensions of the optical axes of the plurality of laser beams at a portion where the beam bundle has been outputted from the output section but has not been converged by the converging lens intersecting with each other at a single point, an intersection of the plurality of laser beams at a portion where the beam bundle has been converged by the converging lens being formed at a position that is closer to the converging lens than a focal point of the converging lens is. |
