The algorithms currently used to control the parameters of light beams and their implementation to numerical experiments aimed at compensating for nonlinear distortions are reviewed. The reasons of the divergence of the algorithm of phase conjugation are discussed. Beam focusing by this algorithm is shown to depend on the chosen integration step along the longitudinal coordinate. The hysteresis dependences of the optical radiation power on the initial power of the light pulse are obtained.
