Abstract

The reported uncertainty is a key parameter in comparing laser damage test results for statistically significant differences. Yet, this important statistic is frequently determined in a nonrigorous manner. This paper presents a Monte Carlo based calculation of the expected distribution of results from a single laser damage threshold (LDT) measurement. The uncertainties in the measured damage frequency and test fluence are used to estimate the probability distributions used in the Monte Carlo model. The model is run many times and the resulting distribution is analzed to yield and estimate the uncertainty in the LDT measurement. It is demonstrated that the distribution of results is not symmetric thus invalidating the use of more conventional closed form formulations for threshold uncertainty.
