The laser beam is moved in relation to the assembly so that the impact point describes a trajectory which corresponds to the desired cutting profile, while maintaining a controlled atmosphere in the area around the impact point. Uses particularly include cutting solid polymer electrolyte lithium thin film electrochemical generators, or cutting precursors of such generators.
