We study the process of masive particle production in a plane wave of massless field of high intensity, in a toy model of two interacting scalar fields. We solve the Heisenberg equation for quantum amplitudes, and find resonantly growing solution similar to parametric resonance. We complement the study A.Arza (PhysRevD.105.036004) in which only the case of small masses has been considered, extending to the case of arbitrary masses. We present the instability threshold for the plane wave amplitude depending on the mass. We have shown that the particle production effect is also observed outside the low-mass approximation.
