It is shown that the rate of development of spatial instability caused by small-scale self-focusing strongly depends on the mutual arrangement of nonlinear media and spatial filters in a setup. The expressions are obtained for the arrangement of elements providing the minimal growth rate of intensity fluctuations. The results of two-dimensional calculations confirm the efficiency of this method of suppressing small-scale self-focusing. (nonlinear optical phenomena)
