In order to provide a laser irradiation system, a method for removing a coating, and a laser irradiation apparatus capable of efficiently removing a coating on a surface of a structure and recovering the removed substance using suction, a laser head () is configured from an optical system () for irradiating laser beam (), a suctioning means () for suctioning removed matter () produced at the point where the laser beam () is directed, and an attachment () configured to be capable of abutting a surface () of a structure, the optical system () being operated to scan the irradiation point of the laser beam so as to draw a trajectory of a circle having a radius raround the optical axis of the laser beam () on a surface substantially perpendicular to the optical axis.

Laser irradiation device, laser irradiation system, and method for removing coating or adhering matter

This is to provide a laser irradiation apparatus which can drive a deflection optical system () with a high speed by a small and lightweight structure and can cope with heat generation of the optical system. The laser irradiation apparatus includes a condensing optical system () for condensing a laser beam (B) generated by a laser oscillator () at a predetermined focal point (FP), a deflection optical system () for deflecting the laser beam (B) generated from the condensing optical system () with a predetermined deflection angle, and a driving unit () for rotationally driving the deflection optical system () around a rotation axis provided substantially in parallel to an optical axis of the condensing optical system (), wherein the driving unit () has an air motor () which convert an energy possessed by a gas supplied from a gas supplying source () to a rotational force.
