Abstract:

Ten dielectric materials were deposited in half-wavelength optically thick films on dielectric substrate with varying surface roughness. The films were subjected to damaging radiation from a TEM mode ND3 in glass laser operating at 1.06 micrometers. The threshold optical field for damage was determined for each film. It was demonstrated that substrate roughness was an overriding consideration in the thin-film thresholds and that no masking of defects by the film was exhibited. Author
