- Аннотация: Terahertz pulse generation in a super-intense laser radiation interaction with a complex nanostructured target consisting of nanowires or nanofoil stripes is studied. During propagation of a relativistic laser pulse along a nanowire (longitudinal interaction), dense high-charge bunches of electrons are forced out of the target and accelerated in the laser field, generating high-power electromagnetic radiation with various spectral composition including terahertz and infrared ranges. Using numerical 2D simulation, characteristics of infrared and terahertz radiation pulses are found for complex nanowire targets. Conversion effciency of the laser pulse energy into the energy of generated radiation is estimated. It is shown that the conversion effciency of the complex target can be several times higher than those for the single nanowire.
