Abstract: A laser-based cleaning system for cleaning generator and turbine parts. In one aspect, the invention includes a system for cleaning blades of a turbine rotor assembly, comprising: a laser positioned remotely from the turbine rotor assembly for generating a laser signal; a laser workhead that receives the laser signal via an optical fiber, wherein the laser workhead is positionable proximate a blade in the turbine rotor assembly and can deliver a laser beam onto a surface of the blade to cause a cleaning of the blade; and a vacuum system for vacuuming debris created by the cleaning.
