In order to provide a laser irradiation system, a method for removing a coating, and a laser irradiation device capable of efficiently removing a coating on a surface of a structure and recovering the removed substance using suction, a laser head (3) is configured from an optical system (4) for emitting laser light (30), a suctioning means (33) for suctioning removed matter (60) produced at the point where the laser light (30) is directed, and an attachment (5) configured to be capable of contacting a surface (20) of a structure, the optical system (4) being operated so as to scan the laser light irradiation in describing a first circular trajectory of a radius r1 centered on the beam axis of the laser light (30) on a surface substantially perpendicular to the beam axis.
