Polarization-sensitive femtosecond laser ablation with tightly focused vortex pulses
We demonstrate that in a tight focusing geometry circularly polarized femtosecond laser vortex pulses ablate material differently depending on the handedness of light. This allows one to control laser micromachining on a sub-wavelength scale.
