Beam waist measurement for terahertz time domain experiments

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Classical variable aperture masking method is not directly applicable to Time Domain Spectroscopy (TDS) experiments. Here, we present a simple and reliable method for measuring beam waists in TDS. It is based on the successive diffraction by an opaque disk followed by a small circular aperture.
