Abstract
Methods and apparatus are provided for igniting, modulating, and sustaining a plasma (615) for coating objects (250). In one embodiment, a method of coating a surface of an object (250) includes forming a plasma (615) in a cavity (230) by subjecting a gas to electromagnetic radiation in the presence of a plasma catalyst (240) and adding at least one coating material (510) to the plasma (615) by energizing the material (510) with, for example, a laser (500). The material (510) is allowed to deposit on the surface of the object (250) to form a coating. Various types of plasma (240) catalysts are also provided.
