Visual art is an integral part of human life, which, like a mirror, reflects the lifestyle and capabilities of a generation. Moreover, each epoch contributes to the development of artistic expression ...techniques. In this article, we discuss three novel approaches to visual art and design from the point of view of modern photonics and laser technology. Laser methods of metal coloring are considered regarding their physical nature, and their ample opportunities for the creation of different artworks are demonstrated.
We offer to use optical features of surface plasmon resonance in Ag nanoparticles for jewelry application as a method for the well-controlled decoration of silver items. The novel approach of silver ...nanoparticles formation with sizes from 5 to 50 nm via nanosecond direct laser writing allows for controlling the reflectance spectra, thus creating a color image on precious metals with a high resolution of about 450 dpi without dyes or hazardous chemicals. Moreover, the large-scale color image can be applied in single-step processing with significant productivity of 2 cm
per minute. This work opens a strong direction for the practical application in the jewelry industry, art, and coining.
Abstract
This work investigates the results of the laser irradiation synthesis of nanoparticles on the gold surface. The sizes and chemical composition of produced nanoparticles were determined, the ...possibility of changing the colorimetric characteristics of the gold surface was shown.
In this work, we have used a nanosecond pulsed fiber laser to modify the wettability characteristics of AISI 430 steel. For this, various surface morphologies were created on the samples by laser ...irradiation with different overlapping and intensity parameters. Immediately upon laser treatment, all the structured samples acquired either hydrophilic or superhydrophilic wetting angles. All the samples were also analyzed with XRD. Then, laser-treated samples were kept in ambient air and/or low-temperature annealing was applied to reach hydrophobic surface properties. Interestingly, these surfaces returned back practically to their initial wetting state by cleaning in an ultrasonic bath. The obtained results are analyzed based on the existing wettability models.
