LASER BEAM CONDENSING UNIT

摘要

PROBLEM TO BE SOLVED: To provide a laser beam condensing unit in which an optical circuit and optical fibers are easily attached/detached at low cost and with good reproducibility.

SOLUTION: The laser beam condensing unit 10 includes: a laser bar 12 having a plurality of light emitting points 20 arranged in an array; an optical circuit 14 for branching or joining laser beams emitted from the laser bar 12 and emitting them; optical fibers 16 for receiving the laser beams emitted from the optical circuit 14 and transmitting them; an optical circuit holder 24 for holding the optical circuit 14; an optical fiber holder 26 for holding the optical fibers 16; and an attaching/detaching mechanism 30 that attaches/detaches the optical circuit holder 24 and the optical fiber holder 26.
