Modeling of off-axis Gaussian beams in elliptical waveguides: application to mode-locking devices

In contrast to the earlier papers devoted to misaligned beams in circular waveguide media, in the present paper we consider an elliptical gradient waveguide with parabolic transverse profile of linear refraction index and Kerr nonlinearity. In our analysis of the beam dynamics we focus our attention at the features promising for application in mode-locking devices.
