摘要：

Laser radiation E = (y) over cap A(z)e(-iwt) propagating through a non-uniform plasma along the direction of the density gradient suffers total reflection at the critical layer. However, when a wiggler magnetic field B-w = (x) over cap B(w)e(ikwz) exists near the critical layer, the laser drives a Langmuir wave. For suitable values of B-w and K-w, the power transfer from the laser to the Langmuir wave could be as high as 60%. The Langmuir wave deposits its energy on the electrons via Landau damping. This may be an efficient mechanism of laser absorption when large self-generated magnetic fields exist in the plasma.
