Measurement of the laser pulse phase velocity in plasma channel for DLA optimization
E. M. Starodubtseva, I. N. Tsymbalov, D. A. Gorlova +3
We demonstrate a novel, direct method for measuring the phase velocity of an intense laser pulse within a plasma channel - the crucial parameter that controls the resonance c…
All-optical blast wave control of laser wakefield acceleration in near critical plasma
I. Tsymbalov, D. Gorlova, K. Ivanov +7
We propose a novel method for changing the length of laser wakefield electron acceleration in a gas jet by a cylindrical blast wave created by a perpendicularly focused nanosecond…
Improving accuracy of field work calculations for the analysis of the electron acceleration mechanisms in near-critical density plasma
Diana Gorlova, Ivan Tsymbalov, Konstantin Ivanov +2
It is demonstrated that the inherent structure of Boris pusher may result in the accumulation of errors in numerical integration when estimating the works of electric fields on par…
THz transition radiation of electron bunch laser-accelerated in long-scale near-critical density plasmas
D A Gorlova, I N Tsymbalov, I P Tsygvintsev +1
Direct laser electron acceleration in near-critical density plasma produces collimated electron beams with high charge (up to C). This regime could be of interest for high e…
Phase space consideration of low energy electron injection for Direct Laser Acceleration
E. Starodubtseva, I. Tsymbalov, D. Gorlova +2
Feasibility of ionization injection for Direct Laser Acceleration (DLA) of electrons up to hundreds of MeV was studied analytically. Criteria for effective injection determining ra…
Hybrid Stimulated Raman Scattering -- Two Plasmon Decay Instability and 3/2 Harmonic in Steep-Gradient Femtosecond Plasmas
I. Tsymbalov, D. Gorlova, A. Savel'ev
The hybrid Stimulated Raman Scattering - Two Plasmon Decay instability had shown to play the dominant role for plasma waves excitation and energy absorption at interaction of very…
