Abstract
An experimental study of few filaments interaction impact on the terahertz radiation pattern has demonstrated that interaction of two close propagating beams leads to formation of a superfilament-like structure with on-axis terahertz yield. Mutual delay between two beamlets tilts the output intensity front of THz emission.

We experimentally study THz emission pattern from complex laser plasma sources formed by several plasma channels
The interaction of two non-delayed beamlets leads to formation of a complex superfilament-like structure, which is characterized by a bright component of THz emission propagating along the axis
