Uncertainty in LIDT Specifications

Laser-induced damage threshold (LIDT) specifications are not an absolute guarantee that damage will not occur below a certain value. Uncertainty in the LIDT value is introduced due to fluctuations in the test laser, the damage detection method, and under sampling the defects on the optic. This uncertainty leads to a confidence interval around the true damage probability as a function of fluence.
