Zusammenfassung:To provide a laser optical system that can form a linear beam having small dimensions in the short dimension even if an optical fiber that transmits the laser light from a laser oscillator has a large core diameter. [Solution] A fiber forwarding laser optical system (1) is configured by means of: a first optical fiber (3) that transmits the laser light outputted from a laser oscillator (2); a collimating lens (4) that collimates the laser light radiated from the first optical fiber (3); a spherical array lens (5) that focuses the laser light radiated from the collimating lens (4) to a multi-point spot by means of a plurality of cells (5a); a plurality of second optical fibers (6) that have a core diameter smaller than that of the first optical fiber (3), input each beam of laser light focused to the multi-point spot by the spherical array lens (5), and are disposed in a linear row with the axial lines of the output ends (6b) thereof being parallel to each other; and an optical system (7-11) that shapes the la
