Abstract: | The shapes of initially spherical Ag nanoparticles in soda-lime glass are persistently changed using fs laser irradiation.
With linearly polarized pulses, this shape transformation of the nanoparticles causes optical dichroism of the material. The
intensity dependence of this effect is studied comprehensively, addressing the whole intensity range of permanent modifications
as well as the influence of the number of laser pulses applied to one spot on the sample. The results are used as basis to
develop a complete scenario of the possible mechanisms leading to the laser-induced shape transformation of metallic nanoparticles
in glass. |
