Abstract

Photoconductors have proved to be extremely effective sources of very short electrical pulses.¹ When illuminated by ultrafast optical pulses they have been used to generate electrical transients as fast as 0.5 ps. The frequency spectrum of these pulses extends from dc up to terahertz frequencies, making them potentially useful sources of microwave, millimeter-wave and far-infrared radiation.
