Abstract
Freely propagating THz pulses are recorded in a thin lithium tantalate crystal by monitoring the phase retardation of a femtosecond probe pulse. This technique permits the determination of the temporal shape of the THz pulse in the picosecond time domain and offers the exciting prospect of up-converting the spatial THz beam profile into the optical wavelength range in real time, with potential application in diagnostics.
