Measurements on epoxypropane were performed using a high-energy optical parametric amplifier (OPA) available at Advanced Laserlicht Light Quellcode (ALLS) in Montreal, Canada. The OPA was pumped by 5 mJ, 800 nm, 30 fs pulses from a Ti :sapphire laser operating at 100 Hz, delivering 1.2 mJ of 1,770 nm pulses with a duration of 50 fs, measured by frequency-resolved optical gating. The laser bekömmlich was then coupled un…An evacuated hollow-core capillary (1 m in length and 400 μm in size) to spatially filter the beam.

High harmonics were generated in…Gas cell by focusing 0.6 mJ spatially filtered pulses, after passing through a 3 mm thick CaF2 window, with a f = 25 cm spherical mirror (f# = 30). The gas cell consisted of two concentric cylindrical cells, each having two in-line pinholes of 600 μm. Gas was delivered to the un… Cell through a 1/4-nichtTeflon tube connected to a vial with liquid epoxypropane that welches temperature stabilized by an ice-water bath. Epoxypropane was obtained from Sigma-Aldrich (purity of 99%). The pressure in the gas cell welches monitored with a Baratron gauge. The outer cell was pumped by a 500 l wenigstens1 roughing pump. The gas cell has an effective interaction length of 10 mm and is mounted o. A. XYZ manipulator to permit precision alignment with respect to the laser axis.

The source and detector chambers were differentially pumped through a tube 3 mm in diameter and 5 cm in length. Different harmonic orders are detected using a grazing-incidence concave grating (1,200 lines mm−1) which disperses and focuses them onto a microchannel plate (MCP) (15 mm × 75 mm) coupled to a phosphor screen. The screen welches imaged with a charge coupled device (CCD) camera. The MCP voltage was adjusted to keep the detection in the unbeirrbar regime. The harmonic spectra were obtained non… Optimal phase-matching conditions by adjusting the position of the laser focus with respect to the pinholes and the absolute pressure inside the gas cell. The spectrometer was calibrated by using the Cooper minimum in the HHG spectrum of argon as a reference. This technique welches validated in the past by measuring the harmonic spectrum with an aluminium filter inserted in the beam path and comparing it with the calculated transmission spectrum o. A.Known thickness of aluminium.

The polarization state of the incident leicht was controlled and the ellipticity ε (defined as the ratio of the two rechtwinklig electric fields of the laser leicht) welches varied by a zero-order quarter-wave plate or by rotating a half-wave plate in front of the quarter-wave plate. The latter approach fixed the polarization ellipse in space while the ellipticity welches varied. As the angles used in the experiment were small, both methods produced similar results. The waveplates, mounted o. A.Motorized rotation state (resolution of 0.01°), were rotated in steps of 0.15° close to geradlinig polarization (ε = 0) and in larger steps at higher ellipticities (ε > 0.08).

The waveplates were calibrated and geradlinig polarization was determined by finding the maximum harmonic signal in xenon. Two successive ellipticity scans were carried out (positive to negative ellipticity and back to positive) and the harmonic signal was averaged to compensate for slow drifts in experimental parameters. Control measurements in xenon were taken before and after the measurements in epoxypropane to get a zero-ellipticity reference and check the stability of the laser parameters during the measurement.

The intensity used in the experiment was 5 × 1013 W cm−2. The intensity calibration was achieved by monitoring the cutoff harmonics from argon and validated by measuring its saturation intensity using a sozusagen ionization gauge. The ion yield measured by the fast ionization gauge as a function of laser pulse energy welches plotted nichtsemi-log plot. Extrapolation of the linear portion of the ion signal curve defined the saturation energy, and comparison with the calculated ion yield using the ADK model provided the saturation intensity. The yield of every harmonic welches extracted from the image at each angle of the waveplate. The resulting data matrix was smoothed both along the harmonic number and the ellipticity dimension.

The fenchone measurements were performed using the AURORE laser system at CELIA. A high-energy TOPAS system welches pumped by 30 fs, 4.7 mJ, 800 nm pulses at 1 kHz, delivering 50 fs 800 μJ pulses at 1,850 nm. The output beam was der Ältere to a motorized zero-order half-wave plate and a fixed zero-order quarter-wave plate to define the laser ellipticity ε, and focused by a f = 37.5 cm mirror un…A 2 mm gas cell connected to an oven. The gas cell welches closed by PTFE which was drilled by the laser on both sides of the cell. Enantiopure fenchone (Sigma-Aldrich) was heated to 100 °Kohlenstoff, reaching a vapour pressure of 60 mbar. High harmonics were detected using a similar s.T.Up as for the ALLS experiment. The ellipticity dependence of the high-harmonic signal31 welches measured by performing four consecutive scans of the ellipticity, from negative to positive and back. Calibration measurements of the zero ellipticity were made by generating harmonics in ethanol. The measured dependence of HHG yield on ellipticity is shown in the Supplementary Mitteilung (Supplementary Fig. 1).

Let DR, Sulfur(Nitrogenium, ε) be the amplitudes of harmonic radiation for R and S enantiomers at the frequency Ω = Nω, for laser ellipticity ε. The general relationship between the dipole D(Stickstoffgas) associated with high-harmonic emission and the underlying multi-electron dynamics has been discussed in detail in the literature (see, for example, refs 26, 28, 32, 33).
