Color Identification

Coloring silver for decorative purposes and for applying identification marks is an important task. In this paper, we consider a method for coloring silver surfaces using VIS plasmonic response in laser-induced nanoparticles (NPs). An analysis was made of the resulted morphology and chemical composition of nanoparticles obtained with nanosecond laser pulses. The dependence of the size and distribution of silver NPs on the laser exposure parameters is determined. The developed color palette was characterized using colorimetric coordinates.

Micro Structuring

Laser interference micro-structuring is a relatively efficient and cost-effective technique for fabricating periodical micro-nano-structuring surfaces. The direct fabrication of sub-micron sized dot array on silicon was performed by four interfering nanosecond laser beams with a diffractive beam splitter. The mechanism to form the dot array was analyzed and it was found that the obtained conical dot array had a negative shape of the interference pattern of four laser beams. A second-order peak between two first-order peaks also occurred due to the liquid-solid expansion.
