The invention discloses a time-division output optical path applied to a high power fiber laser. The time-division output optical path comprises an input fiber (1), a collimating lens (3), a beam refraction translation component (4), a motor (5), mirrors (6), coupling lenses (7) and output fibers (8). The motor (5) drives the beam refraction translation component (4) to move into or out of the optical path, so that a beam comes into different output fibers (8) through different optical paths. According to the invention, the laser beam generated by the same fiber laser can be output to different processing stations on a production line in a time-division manner. The time-division output optical path provided by the invention can reduce power loss caused by offset.
