Screening breakdown in a plasma by two laser fields and strong DC magnetic field

摘要

The effective static dielectric constant of an electron plasma system in the simultaneous presence of two electromagnetic waves and a strong DC magnetic field is calculated. It is found that as the difference Delta omega of the two electromagnetic wave frequencies matches the plasma frequency omega(p) breakdown in screening occurs thereby increasing the plasma heating rate via the external fields due to inverse Bremmstrahlung. An application is made by considering the typical parameters of a hot plasma.
