Abstract
This paper discusses existing and prospective laser devices for countermeasure systems that operate in the IR region. Attention is mainly devoted to questions of counteracting imaging seekers that function in the IR region and of suppressing thermal-vision observation, reconnaissance, and aiming equipment. Our critical analysis of the available literature data makes it possible to conclude that quantum-cascade lasers can be used in creating promising compact multispectral IR countermeasure systems. Estimates are given of how much radiation power quantum-cascade lasers need for the functional suppression of remote photodetector devices. The results of the calculations are in satisfactory agreement with the available literature data. It is shown that existing ways of enhancing the radiation power of quantum-cascade lasers make it possible to achieve the values needed to use them in IR countermeasure systems.
