Formation of Quasi-Unipolar Pulses in Nonequilibrium Magnetized Plasma Channels
摘要
Abstract
An analysis is performed for the possibility of controlling the spectral and polarization properties of THz pulses propagating in strongly nonequilibrium extended magnetized plasma channels formed by intense UV femtosecond laser pulses in nitrogen (air). The formation of quasiunipolar pulses with a nonzero electric area and a specific state of polarization is discussed. The transformation of such pulses upon leaving the region of the static magnetic field is analyzed.
