a–d Surface morphologies of dewetted nanoparticles induced using constant repetition rate (300 kHz) and scan speed (400 mm/s), but different pulse laser powers (2, 6, 8 and 12 W, respectively); e–g corresponding size distributions of nanoparticles; h corresponding absorption spectra. i–l Surface morphologies of dewetted nanoparticles induced using constant repetition rate (100 kHz) and scan speed (400 mm/s), but different pulse laser powers (2, 6, 8 and 12 W, respectively); m–p corresponding size distributions of nanoparticles; q corresponding absorption spectra. All the scale bars are equal to 1 μm
