Journal ArticleDOI
Curved Plasma Channel Generation Using Ultraintense Airy Beams
Pavel Polynkin,Miroslav Kolesik,Jerome V. Moloney,Georgios A. Siviloglou,Demetrios N. Christodoulides +4 more
TL;DR: The experimental observation of curved plasma channels generated in air using femtosecond Airy beams, where the tightly confined main intensity feature of the axially nonsymmetric laser beam propagates along a bent trajectory, leaving a curved plasma channel behind.
Journal ArticleDOI
Evanescent field-based optical fiber sensing device for measuring the refractive index of liquids in microfluidic channels
TL;DR: A simple optical sensing device capable of measuring the refractive index of liquids propagating in microfluidic channels based on a single-mode optical fiber tapered to submicrometer dimensions and immersed in a transparent curable soft polymer, with an estimated accuracy of refractive-index measurement of approximately 5 x 10(-4).
Journal ArticleDOI
Filamentation of femtosecond laser Airy beams in water.
TL;DR: Experiments on the propagation of intense, femtosecond, self-bending Airy laser beams in water reveal the changing character of the laser-pulse evolution on propagation.
Journal ArticleDOI
Standoff spectroscopy via remote generation of a backward-propagating laser beam
Philip R. Hemmer,Richard B. Miles,Pavel Polynkin,T. Siebert,T. Siebert,Alexei V. Sokolov,Phillip Sprangle,Marlan O. Scully,Marlan O. Scully,Marlan O. Scully +9 more
TL;DR: This paper proposes a related but simpler approach on the basis of the backward-directed lasing in optically excited dominant constituents of plain air, N2 and O2, based on the remote generation of a weakly ionized plasma channel through filamentation of an ultraintense femtosecond laser pulse.
Journal ArticleDOI
Supercontinuum generation with femtosecond self-healing Airy pulses.
TL;DR: The ability of the Airy waveform to regenerate its dominant intensity peak results in the generation of distinct spectral features in a highly nonlinear optical fiber.
