Dynamic Bragg microcavities in collisions of unipolar light pulses of unusual shape in two- and three-level medium
Rostislav Arkhipov, Mikhail Arkhipov, Nikolay Rosanov
Unipolar light pulses with a non-zero electric area due to the unidirectional action on charged particles can be used for the ultrafast control of the properties of quantum systems…
Vacuum pair production in zeptosecond pulses: Peculiar momentum spectra and striking particle acceleration by bipolar pulses
I. A. Aleksandrov, N. N. Rosanov
We examine the phenomenon of electron-positron pair production from vacuum in a combination of two counterpropagating electromagnetic pulses having a duration of the order of the C…
Generation and control of population difference gratings in a three-level hydrogen atomic medium using half-cycle attosecond pulses
Rostislav Arkhipov, Mikhail Arkhipov, Nikolay Rosanov
Recently, the possibility of the generation and interaction of unipolar half-cycle electromagnetic pulses with quantum systems has been the subject of active research. Such pulses…
Bragg-like microcavity formed by collision of single-cycle self-induced transparency light pulses in a resonant medium
Rostislav Arkhipov, Anton Pakhomov, Olga Diachkova +2
The coherent interaction of extremely short light pulses with a resonant medium can result in formation of population difference gratings. Such gratings have been created by pulses…
Area theorem in a ring laser cavity
Anton Pakhomov, Mikhail Arkhipov, Nikolay Rosanov +1
The generalization of the area theorem is derived for the case of a pulse circulating inside a ring laser cavity. In contrast to the standard area theorem, which is valid for a sin…
Generation of an ultrahigh-repetition-rate optical half-cycle pulse train in the nested quantum wells
Mikhail Arkhipov, Anton Pakhomov, Rostislav Arkhipov +1
We propose a simple quantum system, namely, a nested quantum-well structure, which is able to generate a train of half-cycle pulses of a few-fs duration, when driven by a static el…
Excitation and control of quantum well nanostructures by unipolar half-cycle attosecond pulses
Rostislav Arkhipov, Pavel Belov, Anton Pakhomov +2
Unipolar and quasi-unipolar half-cycle pulses having nonzero electric pulse area are a limit of pulse shortening in a given spectral range. In spite of the fact that existence of s…
Tailoring the waveshape of optical unipolar pulses in a multi-level resonant medium
Anton Pakhomov, Nikolay Rosanov, Mikhail Arkhipov +1
We theoretically demonstrate the possibility to tune the temporal waveform of optical unipolar pulses upon their coherent interaction with a multi-level resonant medium. This is ac…
Coherently controlled generation of single-cycle terahertz pulses from thin layer of nonlinear medium with low-frequency resonances
R. M. Arkhipov, A. V. Pakhomov, M. V. Arkhipov +4
We propose a novel scheme to generate single-cycle terahertz (THz) pulses via reflection of an optical femtosecond pulse train from a thin layer of nonlinear resonant medium. Our m…
Passive and hybrid mode locking in multi-section terahertz quantum cascade lasers
P. Tzenov, I. Babushkin, R. Arkhipov +4
It is believed that passive mode locking is virtually impossible in quantum cascade lasers (QCLs) because of too fast carrier relaxation time. Here, we revisit this possibility and…
All-optical control of unipolar pulse generation in a resonant medium with nonlinear field coupling
A. V. Pakhomov, R. M. Arkhipov, I. V. Babushkin +3
We study optical response of a resonant medium possessing nonlinear coupling to external field driven by a few-cycle pump pulse sequence. We demonstrate the possibility to directly…
Generation of unipolar pulses in a circular Raman-active medium excited by few-cycle optical pulses
R. M. Arkhipov, M. V. Arkhipov, I. Babushkin +3
We study theoretically a new possibility of unipolar pulses generation in Raman-active medium excited by a series of few-cycle optical pulses. We consider the case when the Raman-a…
