| Abstract: | An experimental study is carried out to investigate a bilateral direct-flow vortex tube of small (0.3–3.0)·10−2 m) size and to compare its optical properties with those characteristics of vortex tubes of a larger ((3–16)10−2 m) scale. A model is suggested for forming transverse profiles of the intensity of laser beams with an intensity hole in the center and of annular beams.
