An algorithm is proposed for optimization of the parameters of propagation of a light beam through a nonlinear medium against the criterion of angular divergence in the far diffraction zone. A system of equations is derived for two auxiliary functions which can be used for construction of an iterative procedure of search for the optimal phase by the method of conditional gradient. To demonstrate the efficiency of the algorithm, the problem of compensation for the stationary wind refraction is solved.
