Soliton pulse compression in the theory of optical parametric amplification

Using inverse scattering transform theory, we obtain new analytical expressions describing the process of parametric amplification by ultrashort pulses. We show that the result of parametric amplification of a small signal pulse by an intense pump wave does not depend on the shape of the pump. The output is determined solely by the intensity of any TWI-solitons contained in the pump. © 1998 Elsevier Science B.V. All rights reserved
