Paper Abstract

There were several references at the 1993 damage conference back to the early days of laser damage studies and in particular to the theoretical paper by E. X. Bliss at the first damage symposium in 1969 on the pulse duration dependence of laser damage mechanisms. However, because of the variations, variability and differences inherent in the measurement of laser- induced damage thresholds this theory has not been used to its full potential. Although the measurement techniques have now been standardized and there is a wider understanding of the mechanisms of LID, the data banks exist mainly in narrow pulse width and wavelength domains. This paper has been written in order to show how the laser test pulse duration affects the measured laser damage threshold and to give, at least, reasonable guidelines for the LIDT's which may be expected for typical materials over a range of pulse lengths.
