Abstract
Optical solitons in media with quadratic nonlinearity and frequency dispers ion are theoretically analyzed. Internal soliton modes and the rate of thei r radiative damping as a function of detuning from the phase-matching condi tion and the nonlinear shift of phase velocity for different soliton dimens ions (d = 1, 2, 3) are found. The length of a nonlinear medium required to form a stationary soliton is determined. (C) 2000 MAIK "Nauka/Interperiodic a".
