The perturbed nonlinear Schrödinger equation model is used to investigate the decay of a strong optical pulse in an absorbing medium with consideration of the nonlinear frequency shift of the pulse. The regularities of the spontaneous soliton production process are investigated numerically. It is established that with the use of the nonlinear frequency shift effect, not only can dissipative losses be compensated in waveguides, but the retarded signal can also be amplified.
