We report what are to our knowledge the first experimental results of coherence enhancement that use polarization to separate coherent and incoherent paths.

The turbulent superresolution effect of a telescope, caused by the focusing properties of a distant turbulent layer, is discussed theoretically and experimentally. This effect is described as follows. Under certain observational conditions the energy

An experimental investigation was made of the angular spectrum and spatial coherence of laser radiation in a turbulent medium. Thermal defocusing increased the spatial coherence radius of the beam field. Experimental results were compared with calcul

The results are given of an experimental investigation of fluctuations in the intensity of a laser beam passing through a turbulent absorbing liquid medium (ethyl alcohol). On increasing the beam power, the intensity fluctuations were found to weaken

An experimental study is done on the evolution of the coherence radius and the intensity fluctuation spectra in time after the transit of a laser pulse through a cell containing an absorbing liquid. The phase front of the radiation up to the nonlinea

Thus, in this paper the results of experimental and theoretical investigations of thermal self-stressing of laser beams in turbulent media were discussed. The following problems were considered: 1) The effect of turbulent agitation on thermal defocus

An experimental investigation was made of the spatial coherence of a laser pulse in a homogeneous medium behind a phase screen. It was found that thermal defocusing resulted initially in an increase in the radius of the spatial coherence of the field
