We demonstrate a table-top high-field terahertz (THz) source based on optical rectification of
a collimated near-infrared pulse in gallium phosphide (GaP) to produce peak fields above …

In recent years several microstructured lithium niobate THz pulse source were suggested for
high-energy applications. Two types of those, the reflective and the transmissive nonlinear …

Terahertz time-domain spectroscopy (THz-TDS) is a powerful technique that enables the
characterization of a large range of bulk materials, devices, and products. Although this …

We report a semiconductor contact grating terahertz source design based on a rectangular
