Abstract :
This study shows methods of stabilisation and control of domain walls in degenerate optical parametric oscillators (DOPO). The first method involves stabilisation of two DWs from noise, with two phase maxima of injected field. The second method consists in introducing dark holes in the transverse profile of the injected pump by using a mask for example. In this way, an outer and an inner boundary limit the pumped region.
