Multiple Filamentation Effects on THz Radiation Pattern from Laser Plasma in Air

Multiple Filamentation Effects on THz Radiation Pattern from Laser Plasma in Air

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 intensit...

Zusammenfassung: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.
