We analyze the simplest dynamical transverse patterns which appear in
Na-2 and CO2 lasers. The experimental values. of the control parameter
s correspond closely to those considered in the theoretical study repo
rted in the companion paper [Brambilla et al., preceding paper, Phys.
Rev. A 49, 1427 (1994)]. We perform a systematic comparsion between th
eoretical predictions and experimental observations.
