Abstract
This work focuses on the optimization of a high reflector design for operation at 1 μm wavelength to achieve a high laser damage threshold when tested at pulse durations of 0.19 and 4 ns. Different designs that modify the standing wave electric field distribution of a quarter wave Ta2O5/SiO2 multilayer dielectric coating are considered. It is found that the addition of an extra SiO2 quarter wave to reduce the peak electric field in the coating, increases the 50% damage probability by over 100% at both pulse durations.
