“…While other direct time-domain optical sampling techniques for visible and near-infrared optical pulses currently exist 10,[12][13][14][15]17 , they require µJ-to mJ-level pulse energies, bulky apparatus, and/or vacuum enclosures. By providing a compact, chip-scale platform that enables sub-cycle, field-sensitive detection of subto few-fJ optical waveforms in ambient conditions, devices similar to those discussed in this work could find applications such as phase-resolved spectroscopy and imaging, and could have an impact in a variety of fields such as biology, medicine, food-safety, gas sensing, and drug discovery.…”

“…Despite these compelling results, scaling such techniques into the near-IR and visible spectral regions has remained challenging. While the manipulation of attosecond electron wave packet emission 10,12,13 and attosecond streaking in the visible to near-IR spectral regions [14][15][16] have proven to be viable paths towards direct optical-field sampling in the time-domain, these techniques are seldom accessible, requiring large driving pulse energies, and accordingly, large laser amplifier systems, bulky apparatuses, and in some cases vacuum environments [10][11][12]17 .…”

We demonstrate an on-chip, optoelectronic device capable of sampling arbitrary, low-energy, near-infrared waveforms under ambient conditions with sub-optical-cycle resolution. Our detector uses field-driven photoemission from resonant nanoantennas to create attosecond electron bursts that probe the electric field of weak optical waveforms. Using these devices, we sampled the electric fields of ~5 fJ (6.4 MV m-1), few-cycle, near-infrared waveforms using ~50 pJ (0.64 GV m-1) near-infrared driving pulses. Beyond sampling these weak optical waveforms, our measurements directly reveal the localized plasmonic dynamics of the emitting nanoantennas in situ. Applications include broadband time-domain spectroscopy of molecular fingerprints from the visible through the infrared, time-domain analysis of nonlinear phenomena, and detailed investigations of strong-field light-matter interactions.

“…They require a second ultrafast laser pulse that can be precisely delayed with the pulse to be measured, and the measurement information is mapped onto the high harmonics, and hence a series of specific XUV spectroscopic measurements is needed for the pulse retrieval. The TIPTOE technique [20] has a simple electrical current readout, but it is similar in that a weak pulse is measured through its perturbing effect, in this case on tunnel ionization in a gas target driven by a stronger field. Although they require elaborate setups, the aforementioned techniques are able to retrieve the full time-dependent optical field, and thus they resolve the pulse carrier envelope phase (CEP), which is not usually accessible with standard benchtop diagnostics, such as SPIDER, FROG, or d-scan.…”

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.

“…Over the recent years, NLO-based techniques have been refined and extended to enable the characterization of single and sub-cycle pulses [14,15]. For example, the trigger of sub-cycle tunnel ionization in air was used to characterize near single cycle pulses [16]. Furthermore, electro-optical sampling [17] has been extended to the near-IR region with the requirement of a sampling pulse which has a duration shorter than the optical cycle of the pulses to be characterized, which is required to be carrier-to-envelop phase stable for multi-shot measurements.…”

In this paper, we introduce a pulse characterization technique that is free of phasematching constraints, exploiting transient absorption in solids as an ultrafast optical switch. Based on a pump-probe setup, this technique uses pump pulses of sufficient intensity to induce the switch, while the pulses to characterize are probing the transmissivity drop of the photoexcited material. This enables the characterization of low-intensity ultra-broadband pulses at the detection limit of the spectrometer, and within the transparency range of the solid. For example, by using zinc selenide (ZnSe), pulses with wavelengths from 0.5 to 20 µm can be characterized, denoting five octaves of spectral range. Using ptychography, we retrieve the temporal profiles of both the probe pulse and the switch. To demonstrate this approach, we measure ultrashort pulses from a titanium-sapphire (Ti-Sa) amplifier which are compressed using a hollow core fiber setup, as well as infrared to mid-infrared pulses generated from an optical parametric amplifier (OPA). The characterized pulses are centered at wavelengths of 0.77, 1.53, 1.75, 4, and 10 µm, down to sub-two optical cycles duration, exceeding an octave of bandwidth, and with energy as low as a few nanojoules.
