Generation and Amplification of THz Radiation in Nonequilibruim Laser Plasma
March 2nd, 2020 ANNA BOGATSKAYA / ALEXANDER POPOV M.V. Lomonosov Moscow State University

We will discuss the process of generation and amplification of short THz pulses taking into account kinetic properties of plasma formed in the process of tunnel ionization by the two-color laser femtosecond pulse, namely velocity distribution of plasma electrons. We will show that the accounting of plasma kinetics can lead to essential variation of the spectral characteristics of generated pulse thus leading to a change in signal duration. The process of subsequent additional amplification of formed seed THz pulse during the propagation through the nonequilibrium Xe plasma channel formed independently by intense femtosecond KrF laser pulse is analysed.
