TL;DR: Phase-matched four-wave mixing in higher-order modes of microstructure fibers allows unprecedentedly high efficiencies of anti-Stokes frequency conversion to be achieved for subnanojoule femtosecond laser pulses.

TL;DR: In this paper, the long-wavelength and visible parts of supercontinuum emission generated by 40 fs pulses of 800 nm Ti : sapphire laser radiation in fused-silica microstructure fibers are shown to be spatially separated in micro-structure-fiber modes.

TL;DR: In this paper, a new design of supercontinuum-generating microstructure fibers is demonstrated, with supercontinuity emission produced in six submicron-diameter cores surrounding a larger central core with a diameter of 2 to 5 μm.

TL;DR: In this article, the authors demonstrate physically different scenarios of nonlinear-optical spectral transformations in the normal and anomalous dispersion regions in microchannel waveguides off the central core in photonic-crystal fibers.

TL;DR: In this paper, the authors used unamplified 35-fs pulses of 820-nm Ti: sapphire laser radiation to demonstrate efficient generation of an intense anti-Stokes signal in an elliptical-core fused silica microstructure fiber.
