Journal ArticleDOI
Nuclear processes in a high-temperature plasma produced by an ultrashort laser pulse
TL;DR: In this article, the experimental data on the initiation of a number of nuclear processes in a plasma produced by an ultrashort laser pulse of intensity 1016-1021 W cm-2 are summarised.
Journal ArticleDOI
Optimization of a femtosecond pulse self-compression region along a filament in air
Olga G. Kosareva,Nikolay Panov,D. S. Uryupina,M. V. Kurilova,Anna Mazhorova,Andrei B Savel'ev,Roman V Volkov,V.P. Kandidov,See Leang Chin +8 more
TL;DR: In this article, the authors identified the self-compression region in a filament produced by 55 fs, 4 mJ, 805 nm radiation propagating in air without geometrical focusing, where the shortest wavelength in the supercontinuum blue wing reaches a minimum and the growing conversion efficiency to white light has a large gradient.
Journal ArticleDOI
Experimental characterization of hot electron production under femtosecond laser plasma interaction at moderate intensities
Vyacheslav M Gordienko,I. M. Lachko,Pavel M Mikheev,Andrei B Savel'ev,D. S. Uryupina,Roman V Volkov +5 more
TL;DR: In this article, the authors discuss methods and algorithms of high-temperature laser plasma electron diagnostics based on hard x-ray yield and ionic time-of-flight (TOF) spectra measurements in comparison with the results of direct electronic spectrum recording, with the help of the electrostatic spectrometer.
Journal ArticleDOI
Pulse shortening due to filamentation in transparent medium
Olga G. Kosareva,I. N. Murtazin,Nikolay Panov,Andrei B Savel'ev,V.P. Kandidov,See Leang Chin +5 more
TL;DR: In this article, the authors show that the full width at half maximum duration of the 45 fs 800 nm pulse becomes 8 fs as soon as the intensity reaches the ionization threshold and that at this propagation distance the compressed pulse accumulates maximum of its energy that is ~4% of the initial pulse energy.
Journal ArticleDOI
Angular distribution of the terahertz radiation intensity from the plasma channel of a femtosecond filament
Nikolay Panov,Olga G. Kosareva,V.A. Andreeva,Andrei B Savel'ev,D. S. Uryupina,Roman V Volkov,Vladimir A Makarov,Alexander P. Shkurinov +7 more
TL;DR: In this article, a phenomenological model of the terahertz radiation of the plasma channel of a femtosecond filament has been elaborated that satisfactorily describes the experimental results of the detection of low-frequency radiation in air.
