Abstract
The ablation damage thresholds for electron beam evaporated HfO2/SiO2 single-, double-, and triple-layer systems of (lambda) /4 optical thickness ((lambda) equals 248 nm) are measured by the pulsed photoacoustic mirage technique. It is shown that the apparent threshold depends on the specific system design and results are interpreted in terms of the electric field distribution in the respective configuration. For one system it is demonstrated that the threshold for the onset of damage measured by the mirage technique can be enhanced by a factor of two when the layers are deposited by laser assisted evaporation technique.
