Abstract
We develop a model of an experiment on pattern formation in a liquid-c rystal light valve with single feedback mirror [E. Pampaloni et al., E urophys. Lett. 24, 647 (1993)]. An analytical treatment based on ampli tude equations explains most of the observed phenomena. Saturation eff ects are needed to describe a secondary bifurcation between triangular and roll patterns.
