It is shown that the nonlinear Schrodinger equation with a source can be investigated by the inverse scattering method for the Dirac operator if the source is represented as the Fourier integral over the eigenfunctions of the so-called generating operator. The obtained results are relevant to some problems of plasma physics and solid state physics.
