Publikováno v: JETP Letters. 115:1-6

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 less attention to. This paper demonstrates possible ways ho

Generation of Ultrashort Attosecond and Terahertz Pulses Based on the Collective Spontaneous Emission from a Thin Resonant Medium (Brief Review)

Autor: Mikhail Arkhipov, Anton N. Tcypkin, N. N. Rosanov, Rostislav Arkhipov, M. O. Zhukova, Anton Pakhomov

Publikováno v: JETP Letters. 113:242-251

Our recent theoretical studies of generation of ultrashort pulses based on collective spontaneous emission from a thin resonant medium layer excited by a pair of high-frequency (compared to the transition frequency of the medium) pulses are reviewed.

Selective Excitation and Creation of Population Inversion in Quantum Systems Using Unipolar Attosecond and Terahertz Pulses

Autor: Rostislav Arkhipov, Mikhail Arkhipov, N. N. Rosanov, M. O. Zhukova, Anton Pakhomov, A. N. Tsypkin

Publikováno v: Optics and Spectroscopy. 129:120-126

The possibility of selective population of the energy levels of quantum systems using a single unipolar subcycle pulse and a pair of pulses has been studied. The possibility of selective population of quantum levels has been clearly illustrated based

Vibrational Nonlinear Response of Liquids Far from Resonance in THz Frequency Range

Autor: Sergei A. Kozlov, Alexandra O. Nabilkova, Anton N. Tcypkin, M. V. Melnik, M. O. Zhukova

Publikováno v: 2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz).

In this work the dispersion of nonlinear refractive index n2 (vibrational third-order nonlinear response) is estimated for various liquids used in THz photonics – water, ethanol, and isopropanol. To calculate n2 we use the theoretical model that co

Pulse Train Generation Dependence on Initial Pulses’ Chirp in THz Frequency Range

Autor: Egor Oparin, Sergei A. Kozlov, Anton N. Tcypkin, M. V. Melnik, M. O. Zhukova

Publikováno v: 2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz).

We demonstrate the dependence of the substructure number in the pulse train and the corresponding frequency comb formed by the interference of two phase-modulated THz pulses on the time delay between pulses for linear and nonlinear chirp cases. The l

Third Harmonic Generation from Liquid Hemisphere on Silicon Substrate in THz Frequency Range

Autor: Polina S. Shaban, Sergei A. Kozlov, Anton N. Tcypkin, M. V. Melnik, M. O. Zhukova, Irina Vorontsova

Publikováno v: 2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz).

In this work third harmonic generation from liquid in terahertz frequency range is addressed. Its generation from a hemisphere of liquid is compared with the one from a layer of water. High generation efficiency is provided by a giant third- order vi
