Spatio-temporal characterisation of laser pulses in the single-cycle regime — •Tobias Witting1,2, Federico Furch1, and Marc J.J. Vrakking11Max-Born-Institut, Max-Born-Strasse 2A, 12489 Berlin — 2Max-Born-Straße 2A

We review spatio-temporal laser pulse characterisation technology for single cycle laser pulses. We show results obtained using spatially-encoded arrangement filter-based spectral phase interferometry for direct electric field reconstruction (SEA-F-SPIDER). We discuss spatio-temporal pulse measurements of hollow fibre-based pulse compressors [1,2] and non-collinear optical parametric chirped pulse amplifier (NOPCPA) laser systems [3]. Recently, we demonstrated pulse characterisation based on time-domain ptychography [4]. We show how time-domain ptychography can be multiplexed for spatio-temporal measurements and compare the results to SEA-F-SPIDER. [1] T. Witting, D.R. Austin, T. Barillot, D. Greening, P.
