Abstract
Transverse pattern formation leading to highly regular structures in both the near and far fields was observed, when a near-resonant laser beam propagates without feedback through an atomic sodium vapor. Honeycomb pattern resulted from the transformation of the laser beam within the vapor into a stable three-lobed structure. The three-filament pattern was found to have a uniform phase profile and strongly correlated power fluctuations.
