  We study second harmonic generation in centrosymmetric Weyl semimetal with
broken time reversal symmetry. We calculate electric current density at the
double frequency of the propagating electromagnetic field in the presence of
applied constant magnetic field, using the method of kinetic equation for
electron distribution function. It is shown that the chiral anomaly
contribution to second harmonic generation in the lowest order is linearly
proportional to the applied magnetic field. The limit when the chiral anomaly
dominates over the Lorentz-type contribution to second harmonic generation is
discussed.
