The fine structure of the vortex-beams in the biaxial and biaxially-induced birefringent media caused by the conical diffraction

Tatyana Fadeyeva, Constantine Alexeyev, Pavel Anischenko +1

We consider the paraxial propagation of nondiffracting singular beams inside natural biaxial and biaxially-induced birefringent media in vicinity of one of the optical axes in term…
