摘要：

We study with the help of numerical simulation the generation of second optical harmonic neglecting group velocity dispersion but taking into account third order dispersion effect at either fundamental or doubled frequency. At that, a component at another frequency usually undergoes second order dispersion in experiments. Varying values and signs of the third order dispersion at quasi-zero values of the second-order dispersion we reveal the conditions of bullet formation and stable propagation.
