Phase-separation dynamics of circular domain walls in the degenerate optical parametric oscillator.
We study the dynamics of the formation of circular domain walls, which are large-intensity structures, in a degenerate optical parametric oscillator. We show that the mean-field and the propagation models predict the same increase in the domain size proportional to t(1/3) .
