Coherent control of the molecular dynamics in a liquid by femtosecond four-pulse excitation

Nikiforov V.; Lobkov V.; Samartsev V.; Saiko A. (2015)

© 2015 Astro Ltd. The laser non-resonant excitation based on the (2 ×2) sequence of the two pairs of the pump pulses with orthogonal linear polarizations is proposed and theoretically considered for the control of the ...
Femtosecond laser control of intramolecular vibrations in a liquid

Nikiforov V.; Shmelev A.; Safiullin G.; Lobkov V.; Samartsev V. (2012)

Optical control of coherent intramolecular oscillations in chloroform CHCl3 and dimethyl sulfoxide (CH 3) 3SO is attained experimentally under normal conditions by means of femtosecond polarization spectroscopy. Nonresonant ...
Implementation of double-pulse laser control in optical Kerr effect spectroscopy

Nikiforov V.; Shmelev A.; Safiullin G.; Lobkov V.; Samartsev V. (2013)

Two-pulse control of time-dependent anisotropy in liquid CCl4 and CHCl3 at room temperature is implemented using femtosecond polarisation spectroscopy. Non-resonant excitation was enhanced by means of the double-pulse ...
Nonresonant double-pulse selective spectroscopy of interaction-induced response in liquids through an optically-heterodyne-detected optical-Kerr-effect

Nikiforov V.; Lobkov V.; Samartsev V. (2015)

© 2015 Astro Ltd. We propose and analyze theoretically the implementation of two pump pulses with orthogonal linear polarization for the separate measurement of an interaction induced response in liquids through the ...
Time-resolved photoinduced charge dynamics of Cd chalcogenide-based materials

Leontyev A.; Nurtdinova L.; Shmelev A.; Zharkov D.; Nikiforov V.; Lobkov V.; Samartsev V. (2019)

© 2018 Astro Ltd. We have performed a comparative analysis of the photocharging dynamics of quantum dots (CdSe-CdS core-shell nanoparticles in toluene) and a bulk CdS single crystal by using time-resolved luminescence and ...
Ultrafast Below-Band-Gap Laser Pulse Induced Relaxations in CdS Crystal

Shmelev A.; Leontyev A.; Nikiforov V.; Ivanin K.; Lobkov V.; Khasanov O.; Samartsev V. (2015)

© Published under licence by IOP Publishing Ltd. We report an experimental study of the intra- and interband transitions in bulk CdS crystal induced by a strong below-band-edge femtosecond laser pulse. An additional peak ...
Ultrafast spectroscopy of CdS/CdSe quantum dots

Shmelev A.; Leontyev A.; Zharkov D.; Nikiforov V.; Lobkov V.; Samartsev V. (2017)

© 2017, Allerton Press, Inc. Results from the nonresonance spectroscopy of CdS/CdSe quantum dots (composites of CdSe–CdS nanoparticles (core–shell)) are presented. The nonlinear optical properties of CdS/CdSe QDs in PMMA ...
