The propagation and transportation of laser beams with radial polarization
(RP beam), possessing a high efficiency in their interaction with matter, a
re studied. The effect of different elements of an optical system on the po
larization state of RP beams is analyzed. It is shown that optical systems
with radial symmetry do not disturb the polarization of an RP beam and that
the negative effect of a mirror on the state of polarization can be counte
rbalanced. (C) 2001 MAIK "Nauka/Interperiodica".
