Abstract

Many of the investigations of contamination related laser damage to date have been largely phenomenological. These papers can provide some direction in the quest for determining and maintaining adequate laser cleanliness levels. Purely optical analyses of laser contamination effects likewise provide direction. Neither the phenomenological nor the purely classical optical methods provide a solid basis for the determination of a safe or acceptable contamination level. This is borne out by the present state of the art. Investigation of the purely physical, optical, or chemical properties of the contamination is insufficient and incomplete. It is necessary to look at the combined physical, chemical and optical properties of the laser system, which includes the contamination. Determination of some key properties of the laser/contaminant system and their interactions has been carried out and the results are promising.
