Terahertz Time Domain Spectroscopy (THz – TDS): Auston Switch / PC detection

Video illustrating the principles of a Terahertz Time Domain Spectrometer (THz – TDS). In the configuration above a Auston Switch is excited by a femtosecond laser pulse to generate a single cycle THz pulse. The electric field of the THz pulse is detected using Oxford’s polarisation sensitive THz detector ( http://dx.doi.org/10.1364/OE.15.007047 ). See http://www-thz.physics.ox.ac.uk for more information
