Optical images of AgNPs written with different numbers of scans. The laser writing power was 5 mW and the energy deposited was 33 J within the 30 × 30 um square. (a) 0.0002 mm/s scan speed, 4 scans, (b) 0.002 mm/s scan speed, 40 scans, (c) 0.004 mm/s, 80 scans, (d) 0.02 mm/s, 400 scans, (e) SEM image of surface made with 80 scans, (f) SEM image of surface made with 400 scans, (g) SEM image of surface made with 80 scans, (h) SEM image of surface made with 400 scans.
