The paper formalizes a model of laser beam control. Working with real equipment implies occurence of various perturbations influencing on optical parameters of the laser beam. This increases divergence of beams and causes diminishing surface density of energy beacause of irradiation and affecting the pointing accuracy of optical navigation systems. One of the approaches to partial compensation of the perturbations influence is using adaptive optical control systems. [1], [6]-[8], [20], [22], [23] In the case it is reasonable to raise the problem of controlling the elements of laser optics system. In the paper this problem is formulated as a differential zero-sum two-person game. The game may be solved by means of analytical and numerical methods.
