Deinert, Jan-Christoph; Kovalev, Sergey; Tielrooij, Klaas-Jan

Research data for used for the publication: "Grating-graphene metamaterial as a platform for terahertz nonlinear photonics".

Datasets measured at the TELBE accelerator-based THz source are measured using a pulse-resolved detection scheme. The data points are sorted according to the absolute arrival time measurement. The four columns hold the following data:
1) absolute time in picoseconds
2) Signal of the emitted THz measured by electro-optic sampling.
3) Relative THz intensity measured using a pyroelectric detector. THz intensity is proportional to absolute power of the signal.
4) Data corresponding to the relative timing of each pulse. Not used for further analysis of the data.

The filenumbers of the measurements used for the figures are as follows:

The datasets measured using a table-top laser source contain two columns. The first one is the position of the optical delay stage in mm that has to be multiplied by 6.667 ps/mm to define the time axis. The second column contains the THz signal as measured using electro-optic sampling.
