Electric field enhancement of nodular defects in multilayer mirrors has been extensively modeled and experimentally validated. However, the impact of reflectance has not been sufficiently explored. Hafnia and silica are the most favored coating materials for high fluence optical and near infrared mirrors. In this study, hafnia and silica mirrors with a reflectance of 0.99, 0.999, 0.9999, and 0.99999 are generated by increasing the layer count >2×. Each of these cases is explored for light intensification at 0° and 45° incidence at both polarizations. The spatial and temporal characteristics of light intensification is examined for these different test cases.
