“…Most synthesized fields of utility for controlling HHG contain spectral components spanning one octave or more. While conventional measurement techniques such as FROG [25], SPIDER [26] and d-scan [27] have been developed that can characterise ultrabroadband pulses, they typically fall short of being able to characterize a synthesized field because they are insensitive to the phase difference between the component pulses. The dynamic range of the measurement techniques must also be very high as even a very weak additional field can significantly affect HHG [28].…”

We have generated isolated attosecond pulses and performed attosecond streaking measurements using a two-colour synthesized laser field consisting of a strong near-infrared few-cycle pulse and a weaker multi-cycle pulse centred at 400 nm. An actively stabilized interferometer was used to coherently combine the two pulses. Using attosecond streaking we characterised the electric fields of the two pulses and accurately retrieved the spectrum of the multi-cycle pulse. We demonstrated a two-fold increase in the flux of isolated attosecond pulses produced and show that their duration was minimally affected by the presence of the weaker field due to spectral filtering by a multilayer mirror.

“…We shall subsequently refer to this new technique as THIS: d-scan (third harmonic in-situ d-scan). Like almost all other pulse diagnostics, it cannot retrieve the CEP, although in situations where the intense pulses have extremely broad bandwidths [42], the resulting overlap between TH and fundamental spectra should enable measuring the CEP stability [43] or retrieving the full optical field and absolute CEP in situ [44]. For HHG driven by few-cycle pulses in gas-jets, the CEP can be sufficiently resolved from a parallel HHG measurement [45], which this technique allows.…”

In laser-matter interaction experiments, it is of paramount importance to characterize the laser pulse on target (in situ) and at full power. This allows pulse optimization and meaningful comparison with theory, and it can shed fundamental new light on pulse distortions occurring in or on the target. Here we introduce and demonstrate a new technique based on dispersion-scan using the concurrent third harmonic emission from the target that permits the full (amplitude and phase), in situ, in-parallel characterization of ultrashort laser pulses in a gas or solid target over a very wide intensity range encompassing the 10 13-10 15 Wcm −2 regime of high harmonic generation and other important strong-field phenomena, with possible extension to relativistic intensities presently inaccessible to other diagnostics.

In addition, the laser amplifier pulses can be further post-compressed in a home-built state-of-the-art hollow-core fiber and chirped-mirror compressor [208], [219]- [222]. In theory, the hollowfiber compressor can generate pulses with sub-4-fs duration, a broadband spectral bandwidth (450-1050 nm), a repetition rate of 1 kHz and an energy per pulse of ~200 μJ.…”

In this work, d-scan was used to measure both the pump and probe pulses of our TR-MOKE system based on the hollow-core-fiber source at the plane of the sample.…”
