Investigation of dynamic and stability of laser-produced plasma in strong external magnetic field.

The paper presents results of studies of the behaviour of a laser-produced plasma in strong external axial and transverse magnetic field of 5-20 T in induction generated from a flat teflon target at the laser power densities of about 10/sup 14/ Wcm/sup -2/. The investigations were carried on by means of three-frame interferometry and a non-contact magnetic probe, the so-called remote magnetic probe (RMP). The dynamics of the process of creation of the diamagnetic cavity, its shape and dimensions have been determined. Also computer simulation of plasma expansion by a 2D MHD code was made.
