Lasers are widely employed in laboratories and in certain industrial applications, notably for welding, cutting and surface treatment. This paper describes a new application, incineration, which appears warranted when the following features are required: high-temperature incineration (> 1500 degree(s)C) with close-tolerance temperature control in an oxidizing medium while ensuring containment of toxic waste. These criteria correspond to the application presented here. Following a brief theoretical introduction concerning the laser/surface interaction, the paper describes the incineration of graphite waste contaminated with alpha-emitting radionuclides. Process feasibility has been demonstrated on a nonradioactive prototype capable of incinerating 10 kg(DOT)h-1 using a 7 kW CO2 laser. An industrial facility with the same capacity, designed to operate within the constraints of an alpha-tight glove box environment, is now at the project stage. Other types of applications with similar requirements may be considered.
