The phenomena in optical pattern formation are reviewed using a single mirror feedback
experiment as an example. The nonlinear medium is sodium metal vapor. We discuss the …

We study spontaneous pattern formation in a system consisting of an alkali-metal vapor cell
placed in front of a feedback mirror and driven by a vector optical field. Through a …

We report the observation of the transition between positive and negative hexagons by
using optical pattern formation in a sodium vapor cell with a feedback mirror. We show that …

In a simple nonlinear optical system consisting of a sodium vapor cell and a single feedback
mirror, the spatial and polarization degrees of freedom are simultaneously unstable if the …

Optical pattern formation in an experiment with single mirror feedback is described. The
nonlinear medium is sodium vapor in a buffer gas atmosphere. A microscopic model is given …

In the transmitted beam of a sodium cell with a single feedback mirror highly modulated
patterns appear. The patterns possess the dihedral symmetries D 6, D 2, and D 3. More …

Quasipatterns with an eightfold rotational symmetry and irregular two-and three-mode
patterns are found in an experiment on optical pattern formation. The patterns exist in the …

Spatio-temporal structures with a regular time dependence are observed in a nonlinear
optical system consisting of a sodium-vapour cell and a single feedback mirror. Target and …

Pattern formation and competition occur in a nonlinear extended medium if dissipation
allows for attracting sets, independently of initial and boundary conditions. This intrinsic …

We report on the observation of localized states (LSs) in a single-mirror feedback system
using sodium vapor as the nonlinear medium. By combining experimental results with …
