According to Einstein-Maxwell-Dilaton theory, the dilaton field $\psi$ can beproduced by electromagnetic fields with non-zero Maxwell invariant. Soelectromagnetic wave propagating in an external electromagnetic field is atypical source of dilaton radiation. For study dilaton photoproduction inastrophysical conditions it's interesting to consider plane ellipticallypolarized electromagnetic wave propagating in the electromagnetic field ofmagnetic dipole ${\bf m}$ of pulsars and magnetars. The dilation field equationis solved in case $|\psi| \ll 1$. The angular distribution dilaton radiation isstudied in every point of space. It's shown that spectral composition ofdilatons is similar to spectral composition of plane electromagnetic wave.Amount of dilaton energy radiated in time and all directions is greatest incondition $(B_1^2-B_2^2)(m_x^2-m_y^2)\geq 0,$ where $B_1$ and $B_2$ areelectromagnetic wave amplitudes along the axes of polarization ellipse. Thiscondition is valid for many neutron star systems.
