  • Publication number: 20230411159
    Abstract: A laser irradiation apparatus according to an embodiment includes an optical module which irradiates an object with laser light so as to form a linear irradiation region along a first direction and a beam damper which absorbs reflected light having been reflected by the object. The beam damper includes a member and a member fixed to the member. The member includes an eaves portion having an opening portion through which the reflected light passes. The eaves portion has a reflection surface which reflects, toward an internal space enclosed by the member and the member, reflected light having been reflected by the object.
