Abstract
The optic layout of a three-channel polarimeter designed to measure th e polarization of an electromagnetic wave probing laser-produced plasm a is described. The space resolution is similar to 5 mu m, and the con trast sensitivity similar to 10(-4). The polarimeter has been used on a plasma produced by the second harmonic of a Nd laser at a power dens ity of similar to 10(15) W/cm(2). The experimental data demonstrate th at the polarization plane is rotated due to the Faraday effect. No inf luence of the electron density gradient on the probe beam's polarizati on has been detected.
