Optical pattern formation in self-focusing and self-defocusing diffractively thick media
G. Labeyrie, I. KreÅ¡iÄ, 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…

Increasing the sensitivity of stellar intensity interferometry with optical telescopes: First laboratory test of spectral multiplexing
S Tolila, G Labeyrie, R Kaiser +2
We present a preliminary laboratory test of a setup designed to measure Hanbury Brown and Twiss-type intensity correlations from a chaotic light source using five spectral channels…
