The model of coherent $\pi^0\pi^0$ mesons photoproduction on simplest nuclei of hydrogen and deiterium in the region $E_{\gamma}\le1.4$ GeV is presented. Two pion rescattering amplitude in process $\pi^+\pi^-\to\pi^0\pi^0$ is taken into account from phenomenological fit is accurately defined it in treshold region as well as up to 1100 MeV relative energy in $\pi\pi$ c.m. Strong dependence of the result on the rescattering amplitude is also discussed.
