Abstract : An experimental study of magnetic signals from laser-produced plasmas was performed. From 2 to 30 joules of laser energy impinged upon metallic and hydrocarbon targets in pulse lengths of from 4 to 80 nanoseconds, and at incident angles of 0 degrees and 45 degrees. Two magnetic signals were detected using inductive probes; one whose peak intensity is temporally coincident with, and whose rise time is a function of the incident laser pulse length; the second longer-lasting and time-delayed from the arrival of the laser pulse on target.
