Аннотация доклада:
New approach to construct the source of THz radiation is discussed. It is based on the formation of induced THz currents by two-color femtosecond optical pulse which are supposed to be injected and amplified in the extended nonequilibrium plasma channel by the mechanism proposed in [1]. The additional gain of the terahertz signal in plasma can ultimately lead to construction of more efficient terahertz sources. The optimal parameters of the pump two-color pulse are investigated and possible realizations of such an amplification scheme are discussed. [1] Bogatskaya A. V., Popov A.
