Shock-induced melting and crystallization in titanium irradiated by ultrashort laser pulse
Vasily Zhakhovsky, Yury Kolobov, Sergey Ashitkov +9
Modification of titanium microstructure after propagation of a melting shock wave (SW) generated by a femtosecond laser pulse is investigated experimentally and analyzed using hydr…
Nonlinear Transfer of Intense Few Cycle Terahertz Pulse Through Opaque n-doped Si
O. V. Chefonov, A. V. Ovchinnikov, M. B. Agranat +4
Intense few cycle terahertz pulses exhibit complex non-linear behavior under interaction with heavily n-doped Si. Fast increase in the transmission of a 700 fs pulse (central frequ…
Giant self-induced transparency of intense few-cycle terahertz pulses in n-doped silicon
O. V. Chefonov, A. V. Ovchinnikov, S. A. Romashevskiy +5
The results of high-field terahertz transmission experiments on n-doped silicon (carrier concentration of cm) are presented. We use terahertz pulses with…
Multi-octave spectrally tunable strong-field Terahertz laser
Carlo Vicario, Andrey V. Ovchinnikov, Oleg V. Chefonov +1
The ideal laser source for the emerging research field of nonlinear Terahertz (THz) spectroscopy should offer radiation with a large versatility and deliver both ultra-intense mult…
Investigation of resonant polarization radiation of relativistic electrons in gratings at small angles
A. N. Aleinik, O. V. Chefonov, B. N. Kalinin +4
The Resonant Optical Polarization Radiation (ROPR) in the Smith-Purcell geometry and the one from the inclined grating at the Tomsk synchrotron and 6-MeV microtron have been invest…
Low-Energy Electron-Beam Diagnostics Based on the Optical Transition Radiation
A. N. Aleinik, O. V. Chefonov, B. N. Kalinin +5
A possibility of a few MeV electron beam diagnostics (Lorentz factor ~ 10) using polarization characteristics of the optical transition radiation (OTR) have been considered. Determ…
