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 …

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

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 …

Progress in the generation of extremely short pulses of electromagnetic radiation makes the
question of the properties of the limiting form of their shorteningÐunipolar pulses with a …

Unipolar and quasi-unipolar half-cycle pulses represent the limit of the pulse shortening in a
given spectral range. So far such pulses have become a subject of active research due to …

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

Progress in reducing the duration of light pulses (down to one cycle of field oscillations or
less), achieved in the last decades, has made it possible to experimentally observe and …

Here we demonstrate an unusual type of superradiance in an extended layer of a two-level
medium excited by a pair of unipolar pulses. It is shown that, due to the interference of …

In recent years, significant progress has been made in generating ultrashort electromagnetic
pulses of single-cycle and subcycle duration. Unipolar pulses contain one half-cycle of the …
