| Summary: | This data set contains raw and processed data for the first proof-of-principle measurements of the ARIES technique. The method and results are fully described in the paper "Attosecond sampling of arbitrary optical waveforms", which has been accepted for publication in Optica (Feb 2016).
All data has been saved as text documents for portability. For multidimensional arrays (>2 dimensions), the data has been split into multiple 2D array files with the filename appended by the extra dimension indices. For example, if the array "intensity" has dimension size [l1 x l2 x l3 x l4], it will be saved as files:
intensity_1_1.dat = intensity(:, :, 1, 1)
intensity_2_1.dat = intensity(:, :, 2, 1)
intensity_1_2.dat = intensity(:, :, 1, 2)
and so on ...
The data has been zipped and compressed by folder.
The contents.txt file lists the contents of all folders.
The LabNotes.zip contains some MS Word documents created during the data acquisition, as well as some processing results. These notes are not complete, but contain useful information and help with orientation.
The files Figx.zip contain all the data necessary to create the figures in the aforementioned paper. Units, where applicable, are indicated by a preceding double underscore in the filename, e.g. "Time__fs.dat" is the temporal axis in [fs]. Single letters preceded by an underscore should correspond to the sub-figure label. E.g. "Fig1/HHG_Int_b__au.dat" corresponds to the HHG spectral intensity in [au] of figure 1b.
The dated zip files contain all the raw data, separated by date of acquisition. Some have been split even further according to the measurement type. Some zip files have been split into multiple parts "filename.zip.part-xx" which need to be joined together before extraction.
The experiments consisted of two campaigns. The first campaign, performed in 2012, correspond to the first proof-of-principle results obtain in argon. After analysing these results and modifying the setup, the second campaign in 2013 was performed in neon. These data sets are extremely large due to saving the full 2D intensity image for each scan position.
** Generally each dataset consists of a scan of the delay between the TP and PP as a function of the TP wedge insertion.
** Data marked "CEP" correspond to small wedge insertions, thus modifying the TP CEP with little change in its temporal intensity.
** Data marked "Dispersion" or "DScan" correspond to large wedge insertions such that the TP temporal intensity changed significantly.
** Data marked "Glass" correspond to when a 1mm thick piece of fused silica was inserted into the TP beam to add significant amounts of dispersion.
** Files marked "Repeatability" should be repeated scans with identical settings (when identified by the same scan number on the same day).
** Files marked "SI" correspond to spectral interferometry measurements between the TP and PP.
** Files mark BP800-40 correspond to measurements made with a 40nm bandpass filter (BPF) centred at 800nm inserted into the TP beam. Files marked "R" had the BPF rotated, resulting in a blue-shift of the bandpass central wavelength.
** Data marked "FDI_CEPScan" correspond to HHG spectral intensity measurements of the PP alone as a function of the PP wedge insertion. These were used to optimize the compression of the PP to give the maximum cut-off energy and ensure a near-cosine PP.
** Data marked "PP_CEP" correspond to ARIES measurements as a function of the PP CEP. Note that changes in the PP CEP were also added to the TP CEP due to the experimental implementation.
