High-frequency periodic patterns driven by non-radiative fields coupled with Marangoni convection instabilities on laser-excited metal surfaces

A Rudenko, A Abou-Saleh, F Pigeon, C Mauclair… - Acta Materialia, 2020 - Elsevier
The capability to organize matter in spontaneous periodic patterns under the action of light is
critical in achieving laser structuring on sub-wavelength scales. Here, the phenomenon of …

Patterns, fronts and structures in a liquid-crystal-light-valve with optical feedback

S Residori - Physics Reports, 2005 - Elsevier
The basic mechanisms of optical pattern formation are reviewed, with particular reference to
a system based on a Liquid-Crystal-Light-Valve with optical feedback. The system is …

Hot atomic vapors for nonlinear and quantum optics

Q Glorieux, T Aladjidi, PD Lett, R Kaiser - New Journal of Physics, 2023 - iopscience.iop.org
Nonlinear optics has been a very dynamic field of research with spectacular phenomena
discovered mainly after the invention of lasers. The combination of high intensity fields with …

Self-organization of light in optical media with competing nonlinearities

F Maucher, T Pohl, S Skupin, W Krolikowski - Physical review letters, 2016 - APS
We study the propagation of light beams through optical media with competing nonlocal
nonlinearities. We demonstrate that the nonlocality of competing focusing and defocusing …

Cubic-quintic condensate solitons in four-wave mixing

Z Wu, Y Zhang, C Yuan, F Wen, H Zheng, Y Zhang… - Physical Review A, 2013 - APS
We experimentally investigate the two-dimensional condensate (optical dropletlike) soliton
formation and dynamics of the generated signal and probe beams in four-wave mixing …

Collapse of hybrid vector beam in Rb atomic vapor

H Hu, D Luo, C Pan, Y Qin, Y Zhang, D Wei, H Chen… - Optics Letters, 2021 - opg.optica.org
In recent years, many researchers have tried to control and design the collapsing behavior
of light beams in nonlinear media. Vector beams coupling with spin and orbit angular …

Photon bubbles in ultracold matter

JT Mendonça, R Kaiser - Physical review letters, 2012 - APS
We show that static and oscillating photon bubbles can be excited by diffused light in the
laser cooled matter confined in a magneto-optical trap. The bubble instability is due to the …

Evaluation of tillage and crop establishment methods integrated with relay seeding of wheat and mungbean for sustainable intensification of cotton-wheat system in …

R Choudhary, P Singh, HS Sidhu, DP Nandal… - Field Crops …, 2016 - Elsevier
Intensive tillage-based conventional cotton-wheat system (CWS) entails high production
costs and has low crop and water productivity thereby threatening its sustainability in the …

Research of far-field diffraction intensity pattern in hot atomic Rb sample

Y Zhang, X Cheng, X Yin, J Bai, P Zhao, Z Ren - Optics express, 2015 - opg.optica.org
In this work we present a study of the far-field diffraction intensity patterns in the Rb atomic
medium. It is found that the far-field diffraction intensity patterns are intimately related to the …

Honeycomb hexagon pattern in dielectric barrier discharge

L Dong, W Liu, H Wang, Y He, W Fan, R Gao - Physical Review E—Statistical …, 2007 - APS
We report on a honeycomb hexagon pattern in dielectric barrier discharge. It bifurcates from
a square pattern as the applied voltage is increased. A phase diagram of the pattern types …
