An all-optical, terahertz characterization based on a ultra-thin-knife-edge is demonstrated employing an ultraviolet-pulse to project the image of a blade on a ZnTe crystal, where the free carriers excited on a blade-shaped area act as a field-shield. © OSA 2013.

Abstract
An all-optical, terahertz characterization based on a ultra-thin-knife-edge is demonstrated employing an ultraviolet-pulse to project the image of a blade on a ZnTe crystal, where the free carriers excited on a blade-shaped area act as a field-shield. © OSA 2013.
