Light is critical for art. It allows us to see color, and can itself be a tool for creating unique pieces of art and design. Here we demonstrate that a laser can be a multifunctional and effective tool for the creation of masterpieces, analogous to the process of an artist creating a canvas with classical paints and brushes. We investigate the interaction between focused laser irradiation and metallic surfaces and analyze the optical effects in thin oxide films for three main artistic operations: color making, multiple color changes, and erasing managed by a nanosecond laser. These processes are possible upon heating the material above the evaporation point and are proved to be dependent on the cooling rate, according to both experimental and theoretical results. Such an interference-based laser paintbrush could find applications in modern art and design.

激光画笔作为现代艺术的工具

光对于艺术至关重要。它使我们能够看到颜色，并且本身就可以成为创造独特艺术品和设计的工具。在这里，我们证明了激光可以成为创作杰作的多功能且有效的工具，类似于艺术家用古典颜料和画笔创作画布的过程。我们研究了聚焦激光辐照与金属表面之间的相互作用，并分析了三种主要的艺术操作在氧化薄膜中的光学效果：制色，多种颜色变化和纳秒级激光管理的擦除。根据实验和理论结果，在将材料加热到高于蒸发点时，这些过程是可能的，并且事实证明，这些过程取决于冷却速率。
