“…Figure 2 summarizes the experimental output pulse durations (FWHM) obtained when scanning the input pulse TOD for the HCF filled with Ar at 0.4 bars (circles) and Ne at 2 bars (asterisks). As expected from previous works [25,26], adding positive TOD to the input pulse allows us to obtain shorter pulses (minimum duration with Ne is 3.4 fs, for TOD 3000 fs 3 and with Ar, 2.7 fs, for TOD 9167 fs 3 ), since the negative TOD from the nonlinear process, mainly the self-steepening, is compensated for. While the Ne cases present longer post-compressed pulse durations compared to the Ar cases, due to a lower nonlinearity at those conditions, the latter are less sensitive to the variation of the input pulse TOD.…”

Strategies for achieving intense single-cycle pulses with in-line post-compression setups

Intense few- and single-cycle pulses are powerful tools in different fields of science Today, third- and higher-order terms in the remnant spectral phase of the pulses remain a major obstacle for obtaining high-quality few- and single-cycle pulses from in-line post-compression setups. In this Letter, we show how input pulse shaping can successfully be applied to standard post-compression setups to minimize the occurrence of high-order phase components during nonlinear propagation and to directly obtain pulses with durations down to 3 fs. Furthermore, by combining this pulse shaping of the input pulse with new-generation broadband chirped mirrors and material addition for remnant third-order phase correction, pulses down to 2.2 fs duration have been measured.

“…This duration is close to the Fourier limit of 2.9 fs (with 60% higher peak power) supported by the broadened spectrum. This is a remarkable result indicating accurate compensation of not only the GDD but also the third-order dispersion (TOD), to which compression in the sub-twooptical-cycle regime is extremely sensitive [35][36][37][38] . As a consequence, venting the d-scan chamber with air is sufficient to spoil the compression shown in Fig.…”

Relativistic-intensity near-single-cycle light waveforms at kHz repetition rate

The development of ultra-intense and ultra-short light sources is currently a subject of intense research driven by the discovery of novel phenomena in the realm of relativistic optics, such as the production of ultrafast energetic particle and radiation beams for applications. It has been a long-standing challenge to unite two hitherto distinct classes of light sources: those achieving relativistic intensity and those with pulse durations approaching a single light cycle. While the former class traditionally involves large-scale amplification chains, the latter class places high demand on the spatiotemporal control of the electromagnetic laser field. Here, we present a light source producing waveformcontrolled 1.5-cycle pulses with a 719 nm central wavelength that can be focused to relativistic intensity at a 1 kHz repetition rate based on nonlinear post-compression in a long hollow-core fiber. The unique capabilities of this source allow us to observe the first experimental indications of light waveform effects in laser wakefield acceleration of relativistic energy electrons.

“…In the negative dispersion regime, it is possible to realize a soliton-like nonlinear self-compression, whereby the negative group delay dispersion of an anomalously dispersive nonlinear medium counteracts the positive group delay dispersion arising from SPM. The output second order dispersion (GDD) resulting from SPM is given by the following formula [38]…”

In attosecond and strong-field physics, the acquisition of few-cycle laser sources open up a new area. We report a nonlinear pulse compression technology combining multi-thin-plate spectral broadening and nonlinear self-compression that generates a 0.52 mJ, good spatial quality characteristics and a spectral bandwidth supporting a 14 fs Fourier transform limited duration at 1 kHz repetition rate and at a center wavelength of 1.9 μm. The total energy transfer efficiency is up to 83%. Pulse to pulse stability of the energy output is 0.7% (RMS). The pulse duration is near 3 optical cycles. This pulse compression approach can be a key-enabling technology for the next generation of extreme photonics, attosecond research and coherent x ray-science, and it also can be further extended to midinfrared lasers with longer wavelengths and higher peak power.
