Strong terahertz radiation generation by beating of two laser beams in magnetized overdense plasma

A New Regime of Anomalous Penetration of Relativistically Strong Laser Radiation into an Overdense Plasma

It is shown that penetration of relativistically intense laser light into an overdense plasma, accessible by self-induced transparency, occurs over a finite length only. The penetration length depends crucially on the overdense plasma parameter and increases with increasing incident intensity after exceeding the threshold for self-induced transparency. Exact analytical solutions describing the ...

Generation of terahertz radiation from ionizing two-color laser pulses in Ar filled metallic hollow waveguides.

The generation of THz radiation from ionizing two-color femtosecond pulses propagating in metallic hollow waveguides filled with Ar is numerically studied. We observe a strong reshaping of the low-frequency part of the spectrum. More precisely, after several millimeters of propagation the spectrum is extended from hundreds of GHz up to approximately 150 THz. For longer propagation distances, ne...
