WebApr 12, 2024 · An electrodynamic system is described that provides the creation of an electromagnetic wave field of high intensity at a frequency of 1 THz due to a combination of accumulation in time and compression in space of a wave pulse coming from an electron cyclotron maser (gyrotron). This system is based on the use of a three-mirror cavity … WebThe observed THz transients are induced through nonlinear electronic processes at gold and silver surfaces on intense pulsed optical photoexcitation and exhibit a peak electric field of as much as 200 V/cm.

WebMar 15, 2014 · Optical rectification (OR) of femtosecond laser pulses in nonlinear crystals is an efficient method for the generation of picosecond THz pulses [4], [5], [6]. The highest so far THz energy (125 µJ) from OR was achieved in LiNbO 3 (LN) [7], by using tilted-pulse-front pumping (TPFP) for velocity matching [8]. WebApr 10, 2024 · One of the most efficient ways of generating terahertz radiation is based on the optical rectification effect in a quadratically nonlinear crystal [1 ... We investigated the soliton-like mode of propagation of an optical-terahertz soliton with tilted wave fronts of the optical component. The tilt angles of the wave fronts were not assumed to be ...
