ABSTRACT
We report on the use of a radially polarized beam for photothermal therapy of cancer cells labeled with gold nanorods. Due to a three-dimensionally distributed electromagnetic field in the focal volume, the radially polarized beam is proven to be a highly efficient laser mode to excite gold nanorods randomly oriented in cancer cells. As a result, the energy fluence for effective cancer cell damage is reduced to one fifth of that required for a linearly polarized beam, which is only 9.3% of the medical safety level.

    The interference of polarized beams in thin CdS crystals placed between crossed polarizers is considered. It is shown that in the case of incomplete polarization of the interfering beams the spectral position of the transmission minimum near the isotropic point depends on the crystal thickness.
