Abstract: The interaction of repetitive nanosecond laser pulses with near-spherical gold nanoparticles, dispersed in an aqueous ambient and having various mean sizes, was studied for two different wavelengths 355 and 532 nm and various energies per pulse. From the in situ surface plasmon (SP), extinction measurements combined with ex situ TEM studies of the irradiated hydrosols, we conclude that the process of laser-induced fragmentation is cumulative with increasing number of subsequent pulses. Interestingly, irradiat…
