The concept of soliton internal mode is introduced to explain quantitatively the long-lived oscillations of self-guided beams, or breathing spatial solitons. Cubic–quintic nonlinearity is considered in detail, and it is shown that the existence of the internal mode affects strongly the beam propagation in non-Kerr media, leading to oscillatory dependence of the output width of the beam versus its input power.

It was also used recently to explain oscillations of two-wave c(2) solitary waves; see C. Etrich, U. Peschel, F. Lederer, B. A. Malomed, and Yu. S. Kivshar, Phys. Rev. E 54, 4321 (1996).
