Abstract

This short paper lays out the goals for a new series of investigations into the proper means of estimating the lifetime of an optic exposed to many, S, laser pulses. The problem of properly identifying a means to estimate component life as important, interesting and being needed is discussed. The fundamental issue in estimation of life is the extrapolation from small to large values of S, frequently this extrapolation is many orders of magnitude. The need for a universal fitting function to enable this extrapolation is the seminal point of these investigations. A key question is the universality of the form of the fitting function. This paper makes the case that such a fitting function requires experimental confirmation. The paper concludes with a call for colleagues to provide such life test data to help in the search of the universal fitting function or functions.
