Unipolar pulses have a nonzero electric pulse area (integral of the electric field strength with
respect of time in a given point of space). Due to unidirectional action on charges they can …

In recent years, progress has been made in obtaining extremely short electromagnetic
pulses up to single-cycle and unipolar half-cycle pulses. For pulses with such a dependence …

The photoionization yield is analyzed for three-dimensional quantum systems with finite
number of discrete spectrum states driven by unipolar subcycle and few-cycle …

We investigate theoretically the nonresonant excitation of vibrational levels in polar
molecules by unipolar radiation pulses of duration much shorter than the characteristic …

Energy, pulse duration, and frequency of the spectral maximum are important characteristics
of pulsed terahertz radiation. The unipolarity of radiation is another characteristic that is paid …

We theoretically demonstrate the possibility to produce unipolar pulses of varying temporal
profile in an extended layer of a resonant medium with the nonlinear coupling to the driving …

We develop a three-dimensional (3D) fully self-consistent model for analysis of an ultrashort
THz pulse propagation and amplification in a nonequilibrium plasma channel formed in …

Важными характеристиками импульсного терагерцевого излучения являются энергия,
длительность импульса и частота спектрального максимума. Еще одной …

В последние годы достигнут прогресс в получении предельно коротких
электромагнитных импульсов вплоть до одноцикловых и униполярных полупериодных …

The propagation of ultrashort electromagnetic pulses with a nonzero electric area in plasma
media is analyzed. An equation for the area of an electromagnetic pulse in the one …
