We obtain and solve algebraic eigenvalue equations that predict the de
pendence of the pulse energy of a dispersion-managed soliton on pulse
duration, chirp, and dispersion-map parameters. We demonstrate that a
variational ansatz based on a Gaussian pulse shape remains useful even
when the actual pulse shape is not Gaussian, and we show that the enh
ancement factor saturates as the pulse duration decreases. (C) 1997 Op
