Abstract

The laser-induced damage threshold (LIDT) determines how optical components are used in a high power laser system, and its uncertainty is key for making comparisons between different LIDT measurements. In this work, we present an analysis of fluence uncertainties of LIDT measurements. The corresponding mathematical expressions for the fluence uncertainties have been established to deal with the statistical data obtained from a one-on-one damage experiment. The results show that the uncertainties are mainly caused by the measurement and calculation of the laser fluence and the damage probability at each fluence level, and the linear fit in a plot of laser fluence versus damage probability.
