Full text of article: Russian language.

Experimental studies of temperature fields were conducted in structural steel 40ХНМА on exposure to laser beams formed by radiation focusators. The Kelvin infra-red thermometer was used to determine temperature in the zone of laser action. The action of the rectangular-shaped moving heat sources provides an opportunity to adjust the maximum temperature values in cross sections of a heat affected zone, whereas increasing density of laser power on edges of rectangle compensates for increasing heat removal from peripheral areas.

Key words:
low-coherent interferometry, Michelson interferometer, scattering and layered media.
