Abstract: | The propagation of partially polarized and partially coherent beams in
uniaxial crystals orthogonal to the optical axis is investigated. The
analytical formulae for the elements of the cross-spectral density matrix of
partially polarized and partially coherent beams propagating through
uniaxial crystals orthogonal to the optical are derived. The numerical
results show that the degree of polarization decreases with the increase of
the ratio of extraordinary to ordinary refractive indices at a certain
propagation distance, and the influence of uniaxial crystals on the degree
of coherent is not so evident. And the beams spread more rapidly in the
direction parallel to the optical axis than orthogonal to the optical axis
in positive crystal with the propagation distance increasing. |
