Y. Horovitz et al., THE INVERSE FARADAY-EFFECT IN PLASMAS PRODUCED BY CIRCULARLY-POLARIZED LASER-LIGHT IN THE RANGE OF INTENSITIES 10(9)-10(14) W CM(2)/, Physics letters. A, 246(3-4), 1998, pp. 329-334
Measurements of the axial magnetic field produced during the interacti
on of circularly polarized laser light with plasma are reported. The e
xperiments were performed with a circularly polarized Nd:YAG laser, wi
th a wavelength of 1.06 mu m and a pulse duration of 7 ns, in a range
of irradiances from 10(9) to 10(14) W/cm(2). Axial magnetic fields fro
m 500 G up to 2.17 MG were measured. Up to 5 x 10(13) W/cm(2) the resu
lts are in agreement with a nonlinear model of the inverse Faraday eff
ect dominated by the ponderomotive force. (C) 1998 Elsevier Science B.
