Method of removing coating film with laser beam and laser processing system

摘要

A laser light is applied to the surface of an object to be processed and formed with a coating film and at least an upper portion of the coating film is removed through abrasion, by using an energy density variable optical system capable of applying the laser light to the surface of the object and varying an energy density of the laser light on the surface of the object. The coating film can be removed without using chemicals.
