| Abstract: | 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 (310–3 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 obtained.__________Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 72, No. 1, pp. 58–62, January–February, 2005. |
