Abstract
Laser ablation cleaning apparatus. An optical box containing mirrors for specially directing laser light, such as repeated pulsed CO2 laser, is mounted in a hand-held cleaning head or in a custom work head. The hand-held cleaning head can be used to safely direct laser energy to a surface to be cleaned; the laser beam ablates from the surface coatings, corrosion, and the like without harming the substrate. The custom work head is removably mountable upon the iron core stack of a conventional commercial electric generator, and features an optics box carriage that is selectively movable along the axis of the stack to direct a laser beam into the slots of the stack for cleaning.
