This activity was started recently. It aims at benefiting of the single atom thickness of graphene to remove propagation effects in laser-matter interaction. The very high mobility of free-carriers in graphene provides a unique system to observe and manipulate the movement of a free-carrier plasma on non-negligible distances.
- Ultrafast laser processing of isolated micro and nano-disks in graphene with single or few pulses. Raman spectroscopy analysis
- Demonstration of a strong drop in ablation probability of graphene at sub-micron dimensions. We have shown the importance of free-carrier diffusion.
