Group interactions of dissipative solitons in a laser cavity: the case of 2+1

Philippe Grelu; Nail Akhmediev (2004)
Publisher: Figshare
What can be the outcome of the interaction between a dissipative soliton pair and a soliton singlet? We report an experimental observation of “elastic” collisions as well as “inelastic” formation of triplet soliton states in a fiber laser setup. These observations are supported with the numerical simulations based on the dispersion (parameter) managed cubic-quintic Ginzburg-Landau equation model.

High-speed measurements of steel-plate deformations during laser surface processing

Matija Jezeršek; Valter Gruden; Janez Možina (2004)
Publisher: Figshare
In this paper we present a novel approach to monitoring the deformations of a steel plate’s surface during various types of laser processing, e.g., engraving, marking, cutting, bending, and welding. The measuring system is based on a laser triangulation principle, where the laser projector generates multiple lines simultaneously. This enables us to measure the shape of the surface with a high sampling rate (80 Hz with our camera) and high accuracy (±7 μm). The measurements of steel-plate defo...

The Dependence of dijet production on photon virtuality in ep collisions at HERA

Chekanov, S.; Derrick, M.; Loizides, J.H.; Magill, S.; Miglioranzi, S.; Musgrave, B.; Repond, J.; Yoshida, R.; Mattingly, M.C.K.; Pavel, N.; Antonioli, P.; Bari, G.; Basile, M.; Bellagamba, L.; Boscherini, D.;... (2004)

DESY-HERA. Measurement of dijet production as a function of the virtuality of the exchanged photon, Q**2, in collisions of 27.5 GeV positrons with 820 GeV protons. The data cover the Q**2 region from 0 to 2000 GeV**2 and come from the 1996 and 1997 HERA running periods with a total integrated luminosity of 38.6 +- 0.6 pb-1. Dijet cross sections were measured for jets with transverse energy & gt; 7.5 and 6.5 GeV and pseudorapidities in the range -3 to 0. The variable X(GAMMA) is used to enhanc...

Microoptomechanical pumps assembled and driven by holographic optical vortex arrays

Kosta Ladavac; David G. Grier (2004)
Publisher: Figshare
Beams of light with helical wavefronts can be focused into ring-like optical traps known as optical vortices. The orbital angular momentum carried by photons in helical modes can be transferred to trapped mesoscopic objects and thereby coupled to a surrounding fluid. We demonstrate that arrays of optical vortices created with the holographic optical tweezer technique can assemble colloidal spheres into dynamically reconfigurable microoptomechanical pumps assembled by optical gradient forces a...
