Laser-material interactions

1. Fundamental understanding of laser-material interactions

A central focus of our research is understanding and harnessing the complex interactions between laser energy and materials across a wide range of timescales and environments. In the Laser & Energy Transport Laboratory, we investigate how different laser parameters—such as wavelength, pulse duration (from quasi-continuous to femtosecond), fluence, and repetition rate—affect material responses including melting, ablation, phase transitions, and micro/nanostructure formation.
