Approximations used in the analysis of signals in pump-probe spectroscopy
Peter Karlsen, Euan Hendry
In pump-probe spectroscopy, one often needs to analyse the transmission or reflection of electromagnetic waves through optically pumped media. Here, it is common practice to approx…

Subwavelength THz imaging of graphene photoconductivity
Samuel M. Hornett, Rayko I. Stantchev, Martha Z. Vardaki +2
Using a spatially structured, optical pump pulse with a THz probe pulse, we are able to determine spatial variations of the ultrafast THz photoconductivity with sub-wavelength reso…
