چکیده
A physical situation is proposed and theoretically analyzed, in which, our opinion, it possible to generate unipolar terahertz pulses with a large electric area. In this case, the gas tube excited by femtosecond IR laser pulse. placed constant external field. The generation of pulse based on "three-step scheme" --- ionization atoms pulse, subsequent acceleration free electron dc field annihilation an upon collision wall or another atom (ion). Keywords: pulses, ultrafast optics, area, radiation, three-step model.

Generation of ultrafast terahertz radiation pulses on metallic nanostructured surfaces.
A resonant "incoherent" rectification process is presented relying on the excitation of surface plasmons on a nanostructured metal surface. Excitation of gold and silver films with 800-nm femtosecond laser pulses results in the emission of terahertz radiation with an angle-dependent efficiency and an approximately third-order power dependence. It is shown that the source of this terahertz pulse...
متن کاملImpulsive terahertz radiation with high electric fields from an amplifier-driven large-area photoconductive antenna.
We report on the generation of impulsive terahertz (THz) radiation with 36 kV/cm vacuum electric field (1.5 mW average thermal power) at 250 kHz repetition rate and a high NIR-to-THz conversion efficiency of 2 x 10(-3). This is achieved by photoexciting biased large-area photoconductive emitter with NIR fs pulses of microJ pulse energy. We demonstrate focussing of the THz beam by tailoring the ...
متن کاملHigh-intensity terahertz radiation from a microstructured large-area photoconductor
We present a planar large-area photoconducting emitter for impulsive generation of terahertz sTHzd radiation. The device consists of an interdigitated electrode metal-semiconductor-metal sMSMd structure which is masked by a second metallization layer isolated from the MSM electrodes. The second layer blocks optical excitation in every second period of the MSM finger structure. Hence charge carr...
متن کاملGeneration of high-power terahertz pulses in a prism.
A compact, high-power emitter of half-cycle terahertz (THz) radiation is demonstrated. The device consists of an epitaxial InAs emitter upon a GaAs prism and produces THz pulses that are 20 times more powerful than those from conventional planar InAs emitters. This improvement is a direct result of reorienting the transient THz dipole such that its axis is not perpendicular to the emitting surf...
متن کاملPhotoacoustic generation of focused quasi-unipolar pressure pulses.
The photoacoustic effect was employed to generate short-duration quasi-unipolar acoustic pressure pulses in both planar and spherically focused geometries. In the focal region, the temporal profile of a pressure pulse can be approximated by the first derivative of the temporal profile near the front transducer surface, with a time averaged value equal to zero. This approximation agreed with exp...
