Transverse magnetic field impact on terahertz wave stimulation in relativistic interaction between hollow gaussian laser beam and collisionless plasma
摘要
This article presents a mathematical model describing the excitation process of terahertz radiation resulting from the relativistic nonlinear interaction of Hollow Gaussian Laser Beam (HGLB) with magnetized collisionless plasma. The effects of laser beam intensity and plasma density on terahertz efficiency conversion have been investigated in the presence of a transverse magnetic field. High terahertz power (reaching GW level) with high stability of terahertz wave has been recorded.
