FIELD: physics.
SUBSTANCE: method of heating thin metal films, implemented using a Mach-Zehnder interferometer scheme, which includes one highly reflective and two semitransparent mirrors, a mirror with phase modulation, as well as a solid-state laser, polarisers for controlling wave amplitude, is characterised by that the surface of the heated metal sample is placed at an angle α to the incident p-polarised laser beam, and said angle is read from the normal to the surface of the sample and has a value at which reflection for a selected material is minimal.
EFFECT: use of the method enables to solve the task of controlling absorption capacity of thin metal samples in the infrared range, and specifically increases efficiency of heating a thin metal film, thereby providing the most optimum heating mode thereof.
