Abstract

The performance of mitigated site coated with antireflective (AR) coating is investigated, and its discrepancy is also investigated by comparing the bare site with substrate from surface morphology and profile, transmittance and laser induced damage threshold (LIDT). The results indicated that more SiO2 sol will be deposited in the crater of mitigated site during the dipping process, while the coated site does not seriously influence the performance of the entire sample. The LIDT results indicate that both the coated substrate and mitigated site are lower than that of un-coated substrate and mitigated site. Keywords: fused silica; mitigated site; coating; sol-gel.
