[en] Gradient-index antireflecting surfaces can be produced by neutral solution processing of bare polished surfaces on borosilicate glasses. These processed surfaces have a median surface damage threshold of 12 J/cm² for 1-ns, 1064-nm pulses. The surface damage thresholds can be increased to fluences as large as 25 J/cm² by irradiating the surface with 1064-nm wavelength pulses at fluences below the initial threshold of 12 J/cm². For surfaces in their initial state, or surfaces subjected to repetitive laser irradiation, surface damage thresholds increased as the square root of pulse duration over the range of pulse durations from 1 to 20 ns
