Abstract
The measurements of local pulsations of brightness temperature T of melt radiance along the front of the cut of metal sheet by CO2 laser are carried out. Both spectrum regions of hydrodynamic and capillary turbulence of temperature fluctuations are shown with experimental estimation of threshold of thermocapillary effect of absorption as 1 MW/cm2.
