Optical pattern formation in self-focusing and self-defocusing diffractively thick media
G. Labeyrie, I. Krešić, R. Kaiser +1
Cold atomic clouds constitute highly resonant nonlinear optical media, whose refractive index can be easily tuned via the light frequency. When subjected to a retro-reflected laser…

Thick-medium model of transverse pattern formation in optically excited cold two-level atoms with a feedback mirror
W. J. Firth, I. Kresic, G. Labeyrie +2
We study a pattern forming instability in a laser driven optically thick cloud of cold two-level atoms with a planar feedback mirror. A theoretical model is developed, enabling a f…
