Abstract

Numerical simulation demonstrates that (2D+1) few-cycle (3–5 oscillations under the envelope) light bullets may form in the medium with quadratic nonlinearity and group velocity anomalous dispersion under conditions of second-harmonic generation. It is shown that as the number of oscillations under the envelope decreases, the parameters of such two-frequency solitons change.
