Abstract

This paper continues an investigation into the applicability of maximum likelihood methods to the problem of laser damage threshold measurement. This year’s investigation applies maximum likelihood methods to an archival set of data and compares two models of damage probability. The Type 1 model has a defined threshold, below which the probability of damage is identically zero, the Type 2 model has finite probability of damage at all fluences. The models are applied to an archival set of data and shown to have similar predictions for the damage threshold, the models differ on the probability of damage at higher fluences. This difference is traced to the fluence selection methods, which in the case of this data set were meant to focus more on the area around threshold. The paper concludes with some next steps in the development of maximum likelihood methods as a laser damage threshold technique.
