Imagine using a laser not just to cut or engrave, but to sculpt matter at the nanoscale. When an intense laser beam hits metals, glasses, or other solids, it can spontaneously generate ripples and grooves only billionths of a metre apart—called laser-induced periodic surface structures (LIPSS). These shimmering nanoscale patterns can create holographic colours, invisible security marks, or surfaces with entirely new optical properties.

In this project, you will explore how to “write” such patterns with light by tuning laser parameters like intensity, pulse duration, and scanning speed. You’ll gain hands-on experience in ultrafast laser processing, nanofabrication, and optical characterization, while learning the fascinating physics of light–matter interaction. The ultimate goal is to design and control tailored nanostructures for advanced applications in anti-counterfeiting, photonics, optical data storage, and smart functional coatings.

This is a project where physics meets creativity—turning focused beams of light into tools for both science and technology.
