Generation of torsional Alfven and slow magnetosonic waves by periodic bunches of laser plasma in a magnetised background

摘要

Using numerical simulation, the influence of parameters of a magnetised background plasma on the intensity of quasi-stationary Alfven and slow magnetosonic waves produced by periodic hunches of a laser plasma in a magnetic field tube is investigated. It is shown that in a weak magnetic field, the waves propagate together, carrying a flow of rotating plasma, and in a strong field, the bunches form simultaneously two types of waves propagating with different velocities.
