Abstract

The composite beam from a 64-element carbon dioxide array laser, which produces an average power output of 2 kW, has been used in a series of surface processing experiments. In one set of experiments related to nuclear power station decommissioning, the array beam has been used to process the surface of a range of different density concrete materials. Scabbling trials have achieved concrete removal rates of ~1200 cm³hr^-1kW^-1 and average scabble depths of ~5 mm with incident power densities as low as 80 Wcm^-2. ©2003 Copyright SPIE - The International Society for Optical Engineering.
