Spatial fluence profile for certification test of laser damage resistance: call for comments

This paper presents a technique for certifying the laser power handling capability of a laser optic. This paper is being presented so that community comments can be collected and incorporated before the issuance of a draft international standard based in the technique defined in the paper in 1997. The paper derives the curve for the probability of the optic surviving a series of exposures to laser irradiation as a function of the laser fluence profile, the number of damage initiation sites on the optic and the fraction of the test optic irradiated at or above a specific level. Of general interest to the community is the discussion of the proper fluence profile for the certification test.
