Frequency doubling of the first type of interaction (oo-e) of intense short laser pulses in crystals with a regular domain structure is numerically studied. The influences of the dispersion of the medium up to the third order and cubic nonlinearity of the Kerr type on the formation of the second harmonic pulse are analyzed. The case is considered when both the conditions of quasi-phase and the equality of the group velocities are simultaneously satisfied. It is shown that in this case an insignificant change of the domain size from the exact value providing the condition of quasi-phase matching leads to a significant increase in the efficiency (almost two time) of second harmonic generation. Numerical calculations show that the latter is due to the compensation of phase shifts caused by the Kerr-type cubic nonlinearity and a change in the size of the domains from the exact value. Lithium niobate with a 5% addition of magnesium oxide (5% MgO:LiNbO3) was chosen as a periodically polarized crystal.
