Subwavelength diffractive optical elements for generation of terahertz coherent beams with pre-given polarization state

HIGHLIGHTS

  • who: Vladimir Pavelyev et al. from the Samara National Research University, Samara, Russia have published the article: Subwavelength Diffractive Optical Elements for Generation of Terahertz Coherent Beams with Pre-Given Polarization State, in the Journal: Sensors 2023, 1579 of /2023/
  • what: The aim of the experiments was to compare the experimentally measured distributions of the local polarization of the beam after passing through the axicon illuminated by linearly polarized radiation and the polarization distribution obtained by numerical simulations.
  • how: The experiments were carried out using the axicons of the first and third orders . . .
