Coherent beam combining of optical vortices
arxiv(2023)
摘要
We experimentally demonstrate the power scaling of optical vortices by the
coherent beam combining, encompassing topological charges ranging from l=1 to
l=5 realized on the basis of a Yb-doped fiber short-pulsed laser system. The
combining efficiency varies from 83.2 to 96.9% depending on the topological
charge and beam pattern quality generated by the spatial light modulators.
These results open a pathway to high-intensity optical vortices with enormous
potential applications in science and industry by utilizing advances in
light-matter interactions.
