Abstract
We investigate stability and dynamics of higher-order solitary waves i n quadratic media, which have a central peak and one or more surroundi ng rings. We show the existence of two qualitatively different behavio rs. For positive phase mismatch the rings break up into filaments that move radially to the initial ring. For sufficient negative mismatches rings are found to coalesce with the central peak, forming a single o scillating filament.
