Polarization-dependent ablation of silicon using tightly focused femtosecond laser vortex pulses. Academic Article uri icon

abstract

  • We demonstrate experimentally that, in a tight focusing geometry, circularly polarized femtosecond laser vortex pulses ablate material differently depending on the handedness of light. This effect offers an additional degree of freedom to control the shape and size of laser-machined structures on a subwavelength scale.
