NSF‑Supported Researcher Uses Femtosecond Lasers to Engineer Functional Materials

In a recent National Science Foundation podcast, Chunlei Guo explained how he employs femtosecond laser pulses to sculpt materials at the atomic scale. The technique allows precise control over the arrangement of atoms, enabling the creation of materials with highly functionalized properties. Guo’s work, funded by NSF, demonstrates a new pathway for designing materials that can be tailored for specific applications. The podcast highlighted the potential of ultrafast laser processing to produce complex material architectures that are difficult to achieve with conventional fabrication methods.
