Laser-induced damage threshold - coating materials and pulse durations

Among the many factors having an influence on the laser-induced damage threshold (LIDT) of optical components are the coating materials used for the optical coating and the pulse duration. In the ns-pulse regime it is relatively easy to scale the LIDT for different pulse durations, but once pulses get shorter than 1 ns, the scaling 'laws' work less and less reliably and the coating material properties themselves become and more and more decisive and LIDT-limiting factor.
The talk will explore the LIDT characteristics and scaling laws a for various pulse durations and explore the influence of the coating materials while suggesting solutions on how to maximise the LIDT of optical coatings given the natural restrictions imposed by the available coating materials.
