Magnetic Reconnection in Laser-Plasma Interactions in a Background Magnetic Field.

Abstract

For laser irradiances I in the ablative regime (I < or = 10 to the 14th power w/sq cm, focused on a small solid target it is shown that magnetic field-reversed configuration, defined by the laser-produced self-generated magnetic field an externally applied magnetic field perpendicular to the laser axis, are possible near the laser-target interaction region. Approximate conditions under which these field-reversed regions undergo driven reconnection are investigated. Magnetic reconnection of the background magnetic field with the laser-induced spontaneous magnetic field can lead to distortion and dissipation of the background magnetic field near the laser-target interaction region. Keywords: Magnetic reconnection; Self generated magnetic field; and Plasma jetting.
