AbstractWe generate space-time coupled attosecond pulse trains with a 1.8 μm wavelength laser pulse using the 'attosecond lighthouse' technique. We show low divergence, spatially well-separated beamlets from low ionization potential gas media. We also find that there is little long trajectory contribution - only the short trajectory contribution is clearly visible for any beamlet. These results open a new route for extending attosecond technology to higher cut off energy and shorter pulse duration. © 2015 IOP Publishing Ltd.
