Abstract
It is demonstrated that Grauss-Laguerre beams with screw wavefront dislocat ions and extraordinary polarization can exist in a uniaxial dichroic crysta l (i.e., a crystal with an angular dependence of linear absorption or gain) . The expressions describing the dependence of the beam width and the wavef ront curvature on the longitudinal coordinate are derived and analyzed. (C) 2001 MAIK "Nauka/Interperiodica".
