“…The measurements of the flame temperature under the conditions of laser beam propagation have shown that in the range of intensities 3.5·10 4 -10 5 W/cm 2 the temperature linearly grows from 2000 to 3000 K. With a further increase in intensity, the temperature rise becomes slower, and at the maximal value of I in = 1.2·10 6 W/cm 2 the temperature becomes equal to 3400 K. For qualitative interpretation of the data presented in figure 3 let us restrict ourselves to considering the influence of solid carbon particles on the radiation transmission [4]. These particles are always present in the hydrocarbon flame in the form of soot [5].…”

Abstract.Mobile laser technological complex MLTC-20 with radiation power 20 kW and radiation wavelength 1.07 µm created in SRC RF TRINITI on the base of a three cw fiber Yb lasers is used successfully at remote cutting of the metalworks at carrying out of the emergency-reduction works on the out of control gas wells. In this work the results of the investigation of the possibility and the efficiency of laser radiation application for remote cutting of metals on the emergency oil wells have been presented.
