The case is considered where low-intensity seed radiation at a frequency close to that of the second harmonic is injected into an optical fiber in addition to the pump radiation. The seed signal is predicted to undergo exponential amplification. The gain has a resonance dependence on the frequency shift. It is shown that the nonlinearity associated with a decrease in the relaxation time taking place with increasing second-harmonic intensity leads to the signal saturation and broadening of the resonance profile. The relation of this effect with the well-known phenomenon of photoinduced second-harmonic generation (SHG) in an optical fiber is discussed. 16 refs., 1 fig.
