Paper Abstract

Variation of the angular spectrum of the laser beam transmitted through the hole formed by it in the glass plate 2 mm thick located in the vicinity of focus of the lens placed into the beam, has been experimentally studied. It has been established that this hole manifests itself as a focusing device and possesses the properties of a short waveguide. The dependence of radiation divergence on the relation between the transverse sizes of the hole and the beam at the inlet has been studied.
