Propagation of diffraction-free and accelerating laser beams in turbid media
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011 We experimentally investigate propagation of laser beams with Gaussian, Bessel and Airy transverse profiles in turbid media. We evaluate and compare the selfhealing properties of these beams.

Generation of High-Power Bottle Beams and Autofocusing Beams
IEEE Photonics Journal, 2018 We propose and experimentally demonstrate an optical bottle beam (BB) and an abruptly autofocusing beam (AB), which were generated using a ring-Airy beam array.

Nondestructive Testing of Welded Composite Metal Foams
Advanced Engineering Materials, EarlyView.X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

Bottle Beams in Nonlocally Defocusing Nonlinear Media
IEEE Photonics Journal, 2019 The dynamics of the inward-focusing ring Airy beam in nonlocally defocusing nonlinear media is investigated in detail, and a bottle beam shape can be observed by adjusting the amplitude of the inward-focusing ring Airy beam and the nonlocality of the ...

Propagation of an Airy beam through the atmosphere
Optics Express, 2013 In this paper, the effect of thermal blooming of an Airy beam propagating through the atmosphere is examined, and the effect of atmospheric turbulence is not considered. The changes of the intensity distribution, the centroid position and the mean-squared beam width of an Airy beam propagating through the atmosphere are studied by using the four ...

Advanced Functional Materials, EarlyView.This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Generation of High-Quality Tunable One-Dimensional Airy Beams Using the Aberrations of a Single Lens
IEEE Photonics Journal, 2012 We designed a highly tunable optical system for generating very good quality 1-D optical Airy beams. The system is composed of only a few passive elements-a microscope objective, a lens, and an aperture stop-so it is easy to align and has no power limits.
