TL;DR: A new Z-scan measurement technique that permits the use of non-Gaussian beams and thick, as well as thin, samples is demonstrated and it is expected that this technique will make possible the measurement of optical nonlinearities by theuse of lasers that previously would have been unsuitable for this purpose.

TL;DR: The predictions of a theoretical model of the filamentation process are in good agreement with observations of transverse pattern formation leading to highly regular structures in both the near and far fields when a near-resonant laser beam propagates without feedback through an atomic sodium vapor.

TL;DR: It is demonstrated that the spatial signatures and phase information of an object with rotational symmetries can be identified using classical orbital angular momentum correlations in random light, and the technique is robust against environmental noise, a fundamental feature of any realistic scheme for remote sensing.

TL;DR: In this paper, it was shown that the CPO effect is sensitive only to intensity variations of the incident laser field that occur on time scales comparable to or shorter than the population relaxation time of the material medium.

TL;DR: It is demonstrated that random fluctuations of intensity give rise to the formation of correlations in the orbital angular momentum components and angular positions of pseudothermal light and suggested that the azimuthal Hanbury Brown and Twiss effect can be useful in the exploration of novel phenomena in other branches of physics and astrophysics.
