Abstract
Variations of the angular spectrum of laser radiation transmitted through a hole produced by this radiation in a glass plate 2 mm thick located near t he focal point of a lens placed in the beam are studied experimentally. It is found that such a hole behaves as a focusing device and possesses the pr operties of a short waveguide. The divergence of radiation is studied as a function of the relation between transverse dimensions of the hole and the input beam.
