| Résumé | We investigate the effects of the laser repetition rate on the creation of angle-independent colours on bulk silver samples, and characterize the coloured surfaces in terms of the associated morphology and oxidation products produced. The laser used produces pulses 10 ps in duration at λ = 1064 nm, and the repetition rate was varied over the range from 5 to 400 kHz. Decreasing the laser repetition rate creates a colour palette on silver with a significantly wider gamut, including green and cyan colours, which were previously difficult to obtain. Scanning electron microscope analyses of these surfaces show an increase in topographical features (roughening) with decreasing laser repetition rate. Chemical analyses of the coloured areas show that the amounts of oxide and carbonate species formed depend on the laser repetition rate. |
