Fiber lasers beyond science and industry
We all recognize the impact of fiber laser technology across various scientific fields. The precision of fiber laser beams has become essential in medicine, telecommunications, and more. Yet, few people are aware of their applications as artistic tools — and this isn’t about restoring old artworks through cleaning techniques.
Fiber lasers can cut intricate patterns in materials such as paper, wood, and metal. These patterns are highly resistant to harsh environments and chemical exposure. Researchers have leveraged these properties to develop a fiber laser system useful for artists and designers.
A research team in Russia recently created a fiber laser paintbrush. This tool enables designers to add, modify, or erase strokes on a titanium canvas with remarkable precision.
Creating colors with fiber lasers
Oxidation-based full-color palette
The device uses fiber laser-induced oxidation to produce a full spectrum of colors on stainless steel — no external pigments are required. The laser forms an oxide layer on the metal surface, with a specific thickness and chemical composition for each color. By carefully adjusting the laser parameters, researchers were able to control color development.
Erasing and rewriting colors
To modify or remove colors, the team designed a printer incorporating a nanosecond ytterbium fiber laser with a scanner to move the beam. Heating the titanium surface with the laser creates an oxide layer, generating colors. A second pass reduces brightness, and slight adjustments to intensity and scanning speed can fully erase the color.
The researchers demonstrated the system by creating several renowned art pieces. What would take traditional artists years to complete could be produced in just three minutes using the fiber laser system.
The team is working on a handheld version of the fiber laser system, allowing artists to use it more like a conventional pen or brush, increasing accessibility and creative freedom.
