Paper Abstract

In high intensity laser systems, molecular contamination represents a risk to the optics. In most situations, molecular contamination is somewhat of a wild card. It is known that it is not required that the contaminant be condensible to initiate damage within a laser system. It is also known that in many cases materials that pass ASTM E-595, are known to precipitate laser optic damage. What has not been known is why. Methods have been developed for the identification, and potential quantitation of trace material emissions that initiate laser optic damage.
