Extreme Sub-Wavelength Structure Formation from Mid-IR Femtosecond Laser Interaction with Silicon
Nanomaterials, 2021 Mid-infrared (MIR) wavelengths (2–10 μμm) open up a new paradigm for femtosecond laser–solid interactions. On a fundamental level, compared to the ubiquitous near-IR (NIR) or visible (VIS) laser interactions, MIR photon energies render semiconductors to ...
