Effect of a strong magnetic field on a laser plasma from a solid target produced in a gaseous atmosphere

The effect of a magnetic field on the dynamics of development of a laser plasma from a target is investigated at various pressures of the ambient gas using streak-camera. The velocity of laser-supported detonation wave in a magnetic field H=170 kOe is higher than is in the case of H=O. The presence of the magnetic field results in a more efficient generation of X-rays by the laser plasma in the focus region. A long-lived hot plasma which cannot expand radially is found to be formed on the optical axis in the magnetic field. It is demonstrated that it should be possible, in principle, to separate plasma bulks with different parameters by means of a magnetic field
