Different methods to control the filamentation zone location of high-power femtosecond laser radiation at its self-focusing in the atmosphere are considered. These are spatial beam focusing, frequency beam modulation, and beam profiling. Solving the nonlinear Schrodinger equation, the range, within which the radiation parameters are to be modified to enable the control of nonlinear beam focus, is determined from the standpoint of the most effective transport of light energy to the receiver.
