摘要
Soliton propagation in a nonlinear cubic medium with two types of relaxing nonlinearities is investigated. Provided that the pulse duration exceeds the fast relaxation time and be shorter than the slow one, partial compensation of the concerted influence of these relaxations on the soliton dynamics is feasible. A condition for such an optimal regime of soliton pulse propagation is analytically obtained. Computer simulations are in good agreement with analytical predictions. (C) 1998 Elsevier Science B.V.
