Abstract
High-power excimer lasers are assembled with individually replaceable optical module subsystems containing consumable optical components. Windows formed in the enclosures of the optical modules incorporate a fluorescent material for converting ultraviolet light scattered from the components of the optical module into visible light emanating from the windows. Changes in the amount or location of the visible light emanating from the windows are interpreted as indications of the degradation in the performance of the optical modules.
