Light is the main source of art around us. It allows us to see colors, and moreover, light itself can be a tool for creating unique pieces of art and designs. Here we demonstrate that a laser acts as a multifunctional and effective tool for creation of masterpieces in a way similar to that of classical paints and brushes. To make analogies between the processes of an artist creating a canvas and laser painting an artwork, we investigate the interaction between focused laser irradiation and metallic surfaces and analyze deeply the optical effects in thin oxide films. For this, we describe the nature of three main artistic operations, which are color making, multiple color change, and erasing managed by a nanosecond laser. These processes are possible due to the material heating above the evaporation point and are proved to be dependent on the cooling rate according to the obtained experimental and theoretical results. Therefore, our work is the first attempt to present the concept of interference-based laser paintbrush, which sets new perspectives for modern art and design.
