THz microscopic imaging is used to extract the Gouy phase shift of the transverse and longitudinal field components of a tightly focused, radially polarized beam. We demonstrate that the applied THz time domain approach allows to observe directly the evolution of the geometric phase as the wave propagates through the focus. Our method yields a Gouy phase shift of 2π for the transverse component and...
We report a significant signal enhancement on the periphery of the probe optical beam in the “heterodyne EO sampling” of pulsed terahertz radiation. Our experimental results coincide with the theoretical prediction. By using this enhancement effect, it is possible to increase the heterodyne EO sampling signal ΔI/I by several folds with optimized detection optics.
