An experimental investigation of the optical properties of a bilateral straight-through-flow small-scale (1.74⋅10−2 m) vortex tube has been carried out experimentally, and the influence of this tube on an axial small-section (3⋅10−3 m) laser beam has been studied. Additional data confirming the reliability of the gas-dynamical model of formation of laser beams with an intensity dip at the center are...
