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 approximately 1200 cm3hr-1kW-1 and average scabble depths of approximately 5 mm with incident power densities as low as 80 Wcm-2.
