Generation of megagauss magnetic fields in laser-target plasmas
- Physics Department, University of Essex, Wivenhoe Park, Colchester CO4 3SQ (United Kingdom)
Many laser-target plasmas are themselves sources of strong, if highly localized, magnetic fields. These fields derive from a number of distinct mechanisms, among them thermoelectric sources, resonance absorption, hot electron fluxes, and the inverse Faraday effect. This review will focus on the best documented of these and on thermo-electrically generated fields in particular since these have been characterized in different parameter regimes. Contemporary concern with sub-picosecond laser plasma interactions for which irradiances can be in excess of 10{sup 18} Wcm{sup {minus}2} has led to renewed interest in the generation of very intense magnetic fields in the range of tens to hundreds of megagauss. Fields of this magnitude would influence the interaction physics significantly, notably with regard to electron thermal transport but also through parametric processes and resonance absorption. {copyright} {ital 1995 American Institute of Physics.}
