学系。 A laser beam transmitted and expanded by an optical fiber is focused by multiple condensing lenses arranged in series across the optical axis, and a rotating mirror is installed in the optical path between the condensing lenses and the focal point. In a laser processing optical system that scans the laser beam irradiated onto the workpiece, a condensing lens placed close to the workpiece is moved in a direction along the optical axis based on the timing of the rotational movement of the rotating mirror. What is claimed is: 1. A laser processing optical system comprising a mechanism for forming a focal point locus of a laser beam scanned by a rotating mirror on a workpiece substantially along a horizontal plane.
