Nonlinear effects on photoinduced phase‐transition domino dynamics in one‐dimensional electron–lattice systems are studied under a condition of the two‐site photoexcitation. The system parameters, i.e. the interaction between atoms, the friction constant, and the distance between the two excited sites, for the domino process to emerge are clarified numerically. It is shown that a region of the existence of the domino dynamics increases significantly in comparison with the case of the single‐site photoexcitation.
